• replacing 3 Cisco Catalyst 4500

  - by hoberion

  Our network supplier recommends replacing our 3 cisco catalyst 4500's because they are EOL and dont speak OSPF (which we really want) Its not my area of expertise so I cant say for sure if we really need to replace these units but for my company the estimated costs of 250K euro is a huge problem. Is there any way to cut down on costs (without moving from cisco devices), I heard the 4500´s can speak ospf but would need an upgrade of sorts? edit: version: IOS (tm) Catalyst 4000 L3 Switch Software (cat4000-I9K91S-M), Version 12.2(20)EW, EARLY DEPLOYMENT RELEASE SOFTWARE (fc1) supervisor: WS-X4013+ Cisco Catalyst 4500 Series Supervisor Engine II-Plus density: WS-X4306-GB Cisco Catalyst 4500 Gigabit Ethernet Module, 6 Ports (GBIC) WS-X4306-GB Cisco Catalyst 4500 Gigabit Ethernet Module, 6 Ports (GBIC) WS-X4548-GB-RJ45 Cisco Catalyst 4500 Enhanced 48-Port 10/100/1000 Module (RJ-45) WS-X4548-GB-RJ45 Cisco Catalyst 4500 Enhanced 48-Port 10/100/1000 Module (RJ-45) WS-X4548-GB-RJ45 Cisco Catalyst 4500 Enhanced 48-Port 10/100/1000 Module (RJ-45)

• Cisco ASA log error "regular translation creation failed for icmp ..."

  - by Martijn Heemels

  Every few seconds our new Cisco ASA 5505 firewall is logging errors that I can't figure out with my limited Cisco experience. Severity Date Time Syslog ID Source IP Destination IP Description 3 Mar 25 2010 17:21:14 305006 8.8.8.8 regular translation creation failed for icmp src inside:10.10.0.200 dst outside:8.8.8.8 (type 3, code 3) 3 Mar 25 2010 17:18:37 305006 8.8.4.4 regular translation creation failed for icmp src inside:10.10.0.200 dst outside:8.8.4.4 (type 3, code 3) The logged inside IP is our internal DNS resolver, and the outside IP's are Google's public DNS servers. ICMP Type 3 Code 3 means "Port Unreachable" Our "outside" interface has a fixed IP and our "inside" interface is in the 10.10.0.0/16 subnet. The 'Inspect DNS' Service Policy is enabled, with the preset DNS inspection map. Furthermore there's an ACL that allows all inbound ICMP on the "outside" interface. I've spent hours trying to figure this one out, so any and all advice is welcome!

• ASA DHCP Relay configuration..

  - by Jeff

  I have locations in different cities, connected using 2 Cisco ASA devices. my main location, corporate, use the IP 192.168.1.x The second location, remote store, use the IP 192.168.3.x I have a DHCP server (192.168.1.254) at my corporate location. I have created a scope for the 192.168.1.x which works fine for the corporate location. I created a scope for the remote location (192.168.3.x) on my DHCP server and tried to configure the remote ASA DCHP Relay, on the remote ASA: I disabled the DHCP Server on the inside. I enabled DHCP Relay on the inside, with set route set at yes. I set the Global DHCP Relay Servers, specify up to four servers to which DHCP requests would be relayed. I added my DHCP, 192.168.1.254 I flashed these settings to the ASA and gave it a try, didn't do anything. am i missing something - forgetting something. not really sure what im doing wrong. DHCP Settings on remote ASA: dhcp-client update dns server both dhcpd dns 192.168.1.254 dhcpd ping_timeout 750 dhcpd domain JEWELS.LOCAL dhcpd auto_config outside dhcpd update dns both ! dhcpd address 192.168.3.2-192.168.3.33 inside ! dhcprelay server 192.168.1.254 outside dhcprelay enable inside dhcprelay setroute inside on my local ASA: i have two ACLs for UDP ports 67 and 68 permitting any inbound traffic from the remote locations IP ... dhcprelay timeout 120

• Cisco FWSM -> ASA upgrade broke our mail server

  - by Mike Pennington

  We send mail with unicode asian characters to our mail server on the other side of our WAN... immediately after upgrading from a FWSM running 2.3(2) to an ASA5550 running 8.2(5), we saw failures on mail jobs that contained unicode. The symptoms are pretty clear... using the ASA's packet capture utility, we snagged the traffic before and after it left the ASA... access-list PCAP line 1 extended permit tcp any host 192.0.2.25 eq 25 capture pcap_inside type raw-data access-list PCAP buffer 1500000 packet-length 9216 interface inside capture pcap_outside type raw-data access-list PCAP buffer 1500000 packet-length 9216 interface WAN I downloaded the pcaps from the ASA by going to https://<fw_addr>/pcap_inside/pcap and https://<fw_addr>/pcap_outside/pcap... when I looked at them with Wireshark Follow TCP Stream, the inside traffic going into the ASA looks like this EHLO metabike AUTH LOGIN YzFwbUlciXNlck== cZUplCVyXzRw But the same mail leaving the ASA on the outside interface looks like this... EHLO metabike AUTH LOGIN YzFwbUlciXNlck== XXXXXXXXXXXX The XXXX characters are concerning... I fixed the issue by disabling ESMTP inspection: wan-fw1(config)# policy-map global_policy wan-fw1(config-pmap)# class inspection_default wan-fw1(config-pmap-c)# no inspect esmtp wan-fw1(config-pmap-c)# end The $5 question... our old FWSM used SMTP fixup without issues... mail went down at the exact moment that we brought the new ASAs online... what specifically is different about the ASA that it is now breaking this mail? Note: usernames / passwords / app names were changed... don't bother trying to Base64-decode this text.

• Is it possible to do DNS-based ACLs on a Cisco ASA?

  - by pickles

  Short of using static IP addresses, is it possible to have a Cisco ASA use a DNS name rather than an IP address? For instance, if I want to limit a host in the DMZ to access only one particular web service, but that web service might be globally load balanced or using DynDNS or cloud, how can the ACL be expressed so that a fixed IP address isn't used and the admin doesn't have to keep opening and closing down IP addresses?

• Monitoring Bandwidth Usage (Per Internal IP) - Cisco ASA 5505

  - by Joseph Sturtevant

  I manage a small network with a Cisco ASA 5505 and a shared DSL connection. I would like to be able monitor the bandwidth usage of the various users/devices on my network (by IP). Can I do that using the ASA? Has anyone got this working? What is the best way to do this? Some Ideas I Have Seen Online: SNMP with a tool like Cacti Does this give per IP usage with an ASA or just overall usage? Netflow with a tool like ntop Couldn't get this to work. It seems that the Netflows sent by ASA are not exactly standard. Ntop receives them, but doesn't seem to know what do with them.

• ASA Slow IPSec Performance with Inconsistent Window Size

  - by Brent

  I have a IPSec link between two sites over ASA 5520s running 8.4(3) and I am getting extremely poor performance when traffic passes over the IPSec VPN. CPU on the devices is ~13%, Memory at 408 MB, and active VPN sessions 2. The load on both of the the devices is particularly low. Latency between the two sites is ~40ms. Screenshot of wireshark file transfer between the two hosts over the firewall IPSec VPN performing at 10MBPS. Note the changing window size. http://imgur.com/wGTB8Cr Screenshot of wireshark file transfer between the two hosts over the firewall not going over IPSec performing at 55MBPS. Constant window size. http://imgur.com/EU23W1e I'm showing an inconsistent window size when transferring over the IPSec VPN ranging in 46,796 to 65535. When performing at 55+MBPS, the window size is consistently 65,535. Does this show a problem in my configuration of the IPSec VPN in the ASA or a Layer1/2 issue? Using ping xxxxxx -f -l I finally get a non-fragment at 1418 bytes so 1418+28 for IP/ICMP headers = 1446. I know that I have 1500 set on the ASA and Ethernet. I do have "Force Maximum segment size for TCP proxy connection to be" "1380" bytes set under Configuration Advanced TCP Options on the ASA. Using IPERF, I am getting a "TCP Window Full" every few seconds and ~3 MBPS performance. http://imgur.com/elRlMpY Show Run on the ASA http://pastebin.com/uKM4Jh76 Show cry accelerator stats http://pastebin.com/xQahnqK3

• ASA 5505 8.4 open ports for subnet

  - by fwrawx

  I have an ASA 5505 running 8.4 with its outside interface plugged into our internal network. I want to open up access to hosts on one of the vlans behind that ASA to hosts on our internal network. I was just starting to grasp NAT on our older PIX but the ASA 8.4 has me confused now. Given a clean ASA with an outside vlan of 10.0.0.1/24 and test vlan of 10.0.1.1/24 what's the basic configuration needed to allow any hosts on the outside network to have access to any of the hosts on the test network?

• How can I forward ALL traffic over a site-to-site VPN on Cisco ASA?

  - by Scott Clements

  Hi There, I currently have two Cisco ASA 5100 routers. They are at different physical sites and are configured with a site-to-site VPN which is active and working. I can communicate with the subnets on either site from the other and both are connected to the internet, however I need to ensure that all the traffic at my remote site goes through this VPN to my site here. I know that the web traffic is doing so as a "tracert" confirms this, but I need to ensure that all other network traffic is being directed over this VPN to my network here. Here is my config for the ASA router at my remote site: hostname ciscoasa domain-name xxxxx enable password 78rl4MkMED8xiJ3g encrypted names ! interface Ethernet0/0 nameif NIACEDC security-level 100 ip address x.x.x.x 255.255.255.0 ! interface Ethernet0/1 description External Janet Connection nameif JANET security-level 0 ip address x.x.x.x 255.255.255.248 ! interface Ethernet0/2 shutdown no nameif security-level 100 no ip address ! interface Ethernet0/3 shutdown no nameif security-level 100 ip address dhcp setroute ! interface Management0/0 nameif management security-level 100 ip address 192.168.100.1 255.255.255.0 management-only ! passwd 2KFQnbNIdI.2KYOU encrypted ftp mode passive clock timezone GMT/BST 0 clock summer-time GMT/BDT recurring last Sun Mar 1:00 last Sun Oct 2:00 dns domain-lookup NIACEDC dns server-group DefaultDNS name-server 154.32.105.18 name-server 154.32.107.18 domain-name XXXX same-security-traffic permit inter-interface same-security-traffic permit intra-interface access-list ren_access_in extended permit ip any any access-list ren_access_in extended permit tcp any any access-list ren_nat0_outbound extended permit ip 192.168.6.0 255.255.255.0 192.168.3.0 255.255.255.0 access-list NIACEDC_nat0_outbound extended permit ip 192.168.12.0 255.255.255.0 192.168.3.0 255.255.255.0 access-list JANET_20_cryptomap extended permit ip 192.168.12.0 255.255.255.0 192.168.3.0 255.255.255.0 access-list NIACEDC_access_in extended permit ip any any access-list NIACEDC_access_in extended permit tcp any any access-list JANET_access_out extended permit ip any any access-list NIACEDC_access_out extended permit ip any any pager lines 24 logging enable logging asdm informational mtu NIACEDC 1500 mtu JANET 1500 mtu management 1500 icmp unreachable rate-limit 1 burst-size 1 asdm image disk0:/asdm-522.bin no asdm history enable arp timeout 14400 nat-control global (NIACEDC) 1 interface global (JANET) 1 interface nat (NIACEDC) 0 access-list NIACEDC_nat0_outbound nat (NIACEDC) 1 192.168.12.0 255.255.255.0 access-group NIACEDC_access_in in interface NIACEDC access-group NIACEDC_access_out out interface NIACEDC access-group JANET_access_out out interface JANET route JANET 0.0.0.0 0.0.0.0 194.82.121.82 1 route JANET 0.0.0.0 0.0.0.0 192.168.3.248 tunneled timeout xlate 3:00:00 timeout conn 1:00:00 half-closed 0:10:00 udp 0:02:00 icmp 0:00:02 timeout sunrpc 0:10:00 h323 0:05:00 h225 1:00:00 mgcp 0:05:00 mgcp-pat 0:05:00 timeout sip 0:30:00 sip_media 0:02:00 sip-invite 0:03:00 sip-disconnect 0:02:00 timeout uauth 0:05:00 absolute http server enable http 192.168.12.0 255.255.255.0 NIACEDC http 192.168.100.0 255.255.255.0 management http 192.168.9.0 255.255.255.0 NIACEDC no snmp-server location no snmp-server contact snmp-server enable traps snmp authentication linkup linkdown coldstart crypto ipsec transform-set ESP-3DES-SHA esp-3des esp-sha-hmac crypto ipsec transform-set ESP-AES-256-SHA esp-aes-256 esp-sha-hmac crypto map JANET_map 20 match address JANET_20_cryptomap crypto map JANET_map 20 set pfs crypto map JANET_map 20 set peer X.X.X.X crypto map JANET_map 20 set transform-set ESP-AES-256-SHA crypto map JANET_map interface JANET crypto isakmp enable JANET crypto isakmp policy 10 authentication pre-share encryption aes-256 hash sha group 2 lifetime 86400 crypto isakmp policy 30 authentication pre-share encryption 3des hash sha group 2 lifetime 86400 crypto isakmp policy 50 authentication pre-share encryption aes-256 hash sha group 5 lifetime 86400 tunnel-group X.X.X.X type ipsec-l2l tunnel-group X.X.X.X ipsec-attributes pre-shared-key * telnet timeout 5 ssh timeout 5 console timeout 0 dhcpd address 192.168.100.2-192.168.100.254 management dhcpd enable management ! ! class-map inspection_default match default-inspection-traffic ! ! policy-map type inspect dns preset_dns_map parameters message-length maximum 512 policy-map global_policy class inspection_default inspect dns preset_dns_map inspect ftp inspect h323 h225 inspect h323 ras inspect rsh inspect rtsp inspect esmtp inspect sqlnet inspect skinny inspect sunrpc inspect xdmcp inspect sip inspect netbios inspect tftp inspect http ! service-policy global_policy global prompt hostname context no asdm history enable Thanks in advance, Scott

• Cisco ASA 5510 ASDM: Setting up multiple public static ip addresses on a single interface and route

  - by ssjaken

  HI, i have a cisco ASA 5510 using ASDM version 6.3 We have a webserver that is been written very specifically and i was given super direct "DO NOT DEVIATE" directions. This server has to get traffic from 3 different PUBLIC ip's that we own. (our isp gave use a block of 12 static addresses) on 4 different ports. there are the directions i was given externalIP1:22 - 172.17.5.50:22 - SSH externalIP1:443 - 172.17.5.50:23040 - SIT externalIP2:443 - 172.17.5.50:33040 - STAGE externalIP3:443 - 172.17.5.50:43040 - PROD My first question is, using ASDM (my contract employer demands i use ASDM over CLI) how do i get three public addresses to work on one interface. We are authenticating on PPPoE. I know create a virtual interface with the static address but when i do i cannot ping the address from another offsite machine. secondly, where would i put the traffic redirect in. would i go ahead and create ACL's or just make NAT routes. Thanks.

• 64-bit Cisco VPN client (IPsec) ?

  - by mika

  Cisco VPN client (IPsec) does not support 64bit Windows. Worse, Cisco does not even plan to release a 64-bit version, instead they say that "For x64 (64-bit) Windows support, you must utilize Cisco's next-generation Cisco AnyConnect VPN Client." Cisco VPN Client Introduction Cisco VPN Client FAQ But SSL VPN licences cost extra. For example, most new ASA firewalls come with plenty of IPSec VPN licences but only a few SSL VPN licences. What alternatives do you have for 64-bit Windows? So far, I know two: 32-bit Cisco VPN Client on a virtual machine NCP Secure Entry Client on 64-bit Windows Any other suggestions or experiences? -mika-

• How can I debug Cisco Firewall ASA "Dispatch Unit" very high CPU utilisation from ASDM?

  - by Andy

  I have recently had my first firewall installed so I am very new to this whole situation. I am finding that Dispatch unit is becoming overloaded and it would appear to be the reason I get serious bouts of lag on my server. The firewall has had little configuration apart from me blocking all the ports in "Access Rules" and allowing only the ones the server needs and from where it needs them. I guess what I am after is assistance with locating the issues causing "Dispatch Unit" to take up all the CPU Regards --Edit-- With ASDM statistics I found that packets inbound (peak of 70-100k/sec from <1k/sec normal), traffic inbound (peak of 40-50kbits/sec from <1kbits/sec normal) and CPU all peak at the same time so I am pretty sure it is an attack of some sort but as a beginner with ASA I am not sure how to resolve

• Cisco ASA 5505 VPN setup

  - by Guillaume

  Hello, I'm trying to setup a site to site VPN, with a Cisco ASA 5505 at one end. The documentation tells me to use the Ipsec VPN wizard but under the wizards drop down menu there's nothing VPN related there. I have a 'base' license, is that the issue? or am I being stupid? The versions I have are: Cisco Asa 5505 with ASA 8.2(1) and ASDM 6.2(1), the firewall was already setup when I got it (I'm leasing a dedicated server). Thanks for your help

• Cisco 837 not passing UDP traffic properly (was: DNS query problem)

  - by TessellatingHeckler

  We have a setup of ADSL line - Cisco 837 ADSL router - Zyxel ZyWall 35 firewall/NAT - Switch - LAN. It has been fine for years, suddenly DNS resolution stopped working from the LAN to public DNS servers. No changes that I know of, so I can't revert anything. Current behaviour: DNS requests from the LAN using TCP show up in the oubound firewall log, in the Cisco debug log, in the dns-server-firewall, in tcpdump on the DNS server, the answer comes back, it works fine. DNS requests from the LAN using UDP show up in the outbound firewall log, in the Cisco debug log, but does NOT show in the dns-server-firewall, not in tcpdump on the DNS server, times out. DNS requests from the Cisco using UDP show up in the dns-server-firewall and in tcpdump on the DNS server, answer received, works fine. netcat connections to port 53 or a random port by TCP show up in the dns-server-firewall netcat connections to port 53 or a random port by UDP do not show up in the dns-server-firewall Summary: TCP seems fine throughought. UDP works from the Cisco over the ADSL, and it works from the LAN to the Cisco, but it doesn't seem to cross the Cisco 837 properly. Update: confirmed with netcat that any UDP traffic from the LAN is affected, not just traffic to port 53. Update: If I change the firewall's external IP to any other IP in the subnet, this starts working. When I put it back, it stops working. I now suspect it's an ISP issue (does that sound plausible?), and am removing the Cisco config.

• Monitoring ASA packet loss via SNMP

  - by dunxd

  I want to monitor packet loss on my ASA 5505 VPN endpoints using SNMP. This is so I can graph the rates in Cacti and/or get alerts in Nagios. However, I am not sure what SNMP values I should use to measure packet loss. In the ASA I can run sh interface Internet stats to show traffic statistics for the interface connected to the Internet. This shows 1 minute and 5 minute drop rates. Are these measures an indicator of packet loss? Are there SNMP values I can access that correspond to those values? Should I be looking at different values? Is the ASA even able to measure packet loss?

• Firewalling a Cisco ASA Split tunnel

  - by dunxd

  I have a Cisco ASA 5510 at head office, and Cisco ASA 5505 in remote offices. The remote offices are connected over a split tunnelled VPN - the ASA 5505s use "Easy VPN" Client type VPN in Network Extension Mode (NEM). I'd like to set firewall rules for the non-tunnelled traffic only. Traffic over the VPN to head office should not have any firewall rules applied. I might want to apply different firewall rules to different remote offices. All the documentation I have been able to find assumes the Client VPN is a software endpoint, and all the configuration is done at the 5510. When using a Cisco 5505 as the VPN client, is it possible to configure any firewalling at the Client end, or does it all have to come from the 5510? Are there any other issues to look out for when split-tunnelling a VPN by this method?

• Cisco ASA - Unable to create "range" type of network object on 8.2

  - by j2k4j

  I'm wanting to block a range of ip addresses on my Cisco ASA 5520 (8.2) using ASDM 6.4. In the help files/cisco documentation, it says, just create a network object with a "range" type, and use that in a blocking access rule... When I'm accessing the ASA (8.2) with ASDM 6.4, I go to configfirewallobjectnetwork objects & groups, then click "add" to add the IP range as a "network object", I get the following 4 fields to fill out: Name: IP address: Netmask: Description: That's all... In the context-sensitive help files, it says that there should be a Type drop-down to select, with "range" being one of the options, but there is no "Type" drop-down list... If I try to create a "network object group" instead of just "network object", then I get a "Type" drop down list, but it only contains two options: network & host (No "Range" option here either) Can someone help me figure out how to block a range of IP's, using the current 8.2 version on the ASA? Thanks for any pointers or tips!

• Outbound Traffic Logging on ASA 5520 possible?

  - by j2k4j

  Taking a look at the ASDM (6.4) for my ASA 5520, I get a nice summary of the traffic status, with items like "interface traffic usage", and "connections per second". This works well, but only shows the data for the last 5-6 minutes or so. Recently, I've been asked whether it's possible to pull up this same type of traffic data for a particular time in the past. (Such as: Find the traffic usage for a 3 minute period from date xx:xx:xx @ time xx:xx:xx) I've noticed that my ASA 5520 is logging the warning, errors, etc that it is processing. But traffic data is not logged (yet) according to my search through the ASA. Is logging the traffic data amounts (as wondered above) actually a possibility? Is there any way to find out the past data for traffic and such values? Thanks!

• Server certificate problem with Cisco AnyConnect VPN Client

• Restore access to Cisco Connect after changing router settings

  - by StasM

  I have recently bought Cisco Valet Plus (M20) wireless router (which I recognize now was a mistake, but nevermind). It has two setup options - Cisco Connect software and web-based setup. Cisco Connect software allows changing very small set of settings, web-based setup allows access to almost all settings, except settings for guest network. The problem is that when I use web-based setup, Cisco Connect after some changes refuses to talk to the router, so I can't change guest settings anymore (since web interface doesn't allow to change them). It must be because of some config parameter not matching or some password set wrong - but I don't know where Cisco Connect stores them. So, does anybody have any idea how to make Cisco Connect talk to the router again once I changed the settings through the web interface?

Interrupted by client, cause: The process cannot access the file 'C:\TFTP-Root\t' because it is being used by another process I've used tftpd32 with same results.
