  • Why should I use Firewall Zones and not just Address Objects?

    - by SRobertJames
    I appreciate Firewall Address Objects and Address Groups - they simplify management by letting me give a name to a group of addresses. But I don't understand what Firewall Zones (LAN, WAN, DMZ, etc.) do for me over Address Groups. I know all firewalls have them, so there must be a good reason. But what do I gain by stating a rule applies to all traffic from LAN Zone to WAN Zone which comes from LAN Address Group to WAN Address Group? Why not just mention the Address Groups?

  • Just one client bound to address and port: does it make a difference broadcast versus unicast in terms of overhead?

    - by chrisapotek
    Scenario: I am implementing failed over for a network node, so my idea is to make the master node listens on a broadcast ip address and port. If the master node fails, another failover node will start listening on this broadcast address (and port) and take over. Question: My concern is that I will be using a broadcast IP address just for a single node: the master. The failover node only binds if the master fails, in other words, almost never. In terms of network/traffic overhead, is it bad to talk to a single node through a broadcast address or the network somehow is smart enough to know that nobody else is listening to this broadcast address and kind of treat it as a unicast in terms of overhead? My concern is that I will be flooding my network with packets from this broadcast address even thought I am just really talking to a single node (the master). But I can't use unicast because the failover node has to be able to pick up the master stream quickly and transparently in case it fails.

  • How to force Windows 7 to ask for a "fresh" IP address from DHCP server?

    - by haimg
    I'm troubleshooting a certain issue with my DHCP configuration, and need my Windows machine to ask for a "fresh" IP address, so I can see which address DHCP server gives by default. When I do ipconfig /release followed by ipconfig /renew, Windows "proposes" its old IP address to the DHCP server (just checked with Wireshark, initial "DHCP Discover" message has Option-50 (requested IP address) with Windows machine's old IP). Tried disabling/enabling network adapter. Same behavior. Question: How can I force Windows to just ask for a new IP address, without proposing its old IP address.

  • How does a frame retrieve the recipient's MAC address?

    - by Sarmen B.
    I am studying a Network+ book named All-in-one CompTia Network+ by Mike Meyers. In chapter 2 he talks about frames and how he represents them as canisters and the data within the frame contains the recipients mac address, senders mac address, data, and sequence number. What I don't understand is if the sender is sending a file via the network to the recipient, and this frame contains this data, how does the frame know what the recipients MAC address is before sending it? In regards to TCP/IP when it contains the recipients IP address, that's understandable how it retrieves that value. But I don't understand how it can retrieve the MAC address, because if that frame comes from the senders computer, goes into the router and copies itself to each and every computer that exists on the network, how did it have the MAC address to know where to go? Let me know if I'm not making sense.

  • Why doesn't disabling IE's 'Protected Mode' enable the dragging-and-dropping of addresses from the IE address bar into Notepad

    - by dumbledad
    IE's Protected Mode prevents one dragging the address from the IE address bar into other applications (for example Notepad). There's an informative article on MSDN about Allowing Drag and Drop Operations in your Application. If I uncheck Enable Protected Mode in IE's settings and restart IE I still cannot drag the address from the IE address bar into other Notepad. Why doesn't disabling IE's 'Protected Mode' enable the dragging-and-dropping of addresses from the IE address bar into Notepad? Is there a way to make that work without adding a registry entry for Notepad (following the instructions in the article I mentioned)? (N.B. This is actually part of me trying to work out how to get this address drag-and-drop working in Processing.)

  • Can't connect to local IP address on OSX

    - by Alex Worden
    I'm trying to connect to a webserver that's running on my mac OSX 1.6. I'm able to connect to it locally using http://127.0.0.1:8888/myapp but when I attempt to connect to it using my machine's local IP address (http://192.168.1.15:8888/myapp IP shown below) from the same machine (or another on the network) I cannot connect. I can ping the LAN IP address. I've tried adding IP forwarding to my router for port 8888 but it didn't help. I've checked and the OSX firewall is disabled Can anyone suggest what else is blocking the connection? Here's what I get when I run ifconfig: ~ :ifconfig lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1 inet 127.0.0.1 netmask 0xff000000 gif0: flags=8010<POINTOPOINT,MULTICAST> mtu 1280 stf0: flags=0<> mtu 1280 en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether 00:1f:5b:e8:16:4d media: autoselect status: inactive supported media: autoselect 10baseT/UTP <half-duplex> 10baseT/UTP <full-duplex> 10baseT/UTP <full-duplex,hw-loopback> 10baseT/UTP <full-duplex,flow-control> 100baseTX <half-duplex> 100baseTX <full-duplex> 100baseTX <full-duplex,hw-loopback> 100baseTX <full-duplex,flow-control> 1000baseT <full-duplex> 1000baseT <full-duplex,hw-loopback> 1000baseT <full-duplex,flow-control> none en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet6 fe80::21e:c2ff:febf:4809%en1 prefixlen 64 scopeid 0x5 inet 192.168.1.15 netmask 0xffffff00 broadcast 192.168.1.255 ether 00:1e:c2:bf:48:09 media: autoselect status: active supported media: autoselect fw0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 4078 lladdr 00:1f:5b:ff:fe:2b:b3:3c media: autoselect <full-duplex> status: inactive supported media: autoselect <full-duplex> en5: flags=8822<BROADCAST,SMART,SIMPLEX,MULTICAST> mtu 1500 ether 00:1e:c2:8e:0f:45 media: autoselect status: inactive supported media: none autoselect 10baseT/UTP <half-duplex> en2: flags=8922<BROADCAST,SMART,PROMISC,SIMPLEX,MULTICAST> mtu 1500 ether 00:1c:42:00:00:00 media: autoselect status: inactive supported media: autoselect en3: flags=8922<BROADCAST,SMART,PROMISC,SIMPLEX,MULTICAST> mtu 1500 ether 00:1c:42:00:00:01 media: autoselect status: inactive supported media: autoselect

  • Git - ssh key / ip address

    - by Steve
    When I set up Git, I did it while using a dsl modem, and my ip isn't static, so when I generated the ssh keys for Git, it was based on that ip. When I'm assigned an ip other than the one used to generate the ssh Git keys, I can manually change the ip address to the one used to generate the keys. What are my other options to bypass this step? Dynamic DNS? Is there another way?

  • Outlook email address autocompletion slow

    - by user214984
    Hello, I'm using outlook 2007. Two days ago, we've enabled auto-archiving, maybe that't the source of our problems, but I still have to investigate. At any rate, auto completion of email addresses in the to/cc/bcc fields has become a stopper, taking up to a minute to do something. I've searched the web, but found only references to problems with McAfee which I don't have installed (http://www.groovypost.com/howto/microsoft/outlook/fix-slow-outlook-email-address-auto-complete/) Thanks Holger
