What I have:
A linksys router WAG160N with firmware version 2
A "pool" of 5 external static IP's provided by my ISP 213.xx.xxx.n
All the required configuration values for the static IPs such as (Subnet Mask, Gateway and static DNS 1, 2, 3)
Current WAN Configuration:
Encapsulation: RFC 2364 PPPoA
Multiplexing: VC
QoS type: UBR
DSL modulation: MultiMode
What's connected to the network:
1 x Server (That I want to make available to the outside)
5 x Desktops with static internal IP's, such as 192.168.0.xx
2 x Network printers, also with internal static IP's
2 x Laptops
1 x NAS (Network Attached Storage) also on static IP
What I want to do:
I would like to make the server available from outside the network, for example from your house. The problem is that Im not really sure how to do this. I have tried following the steps on the instruction manual in Linksys but they do not seem to work, once I set it up as shown bellow, I loose internet and all hell breaks loose.
Going into further detail, I would prefer if the network is changed as little as possible, by this I mean that all the computers stay networked within eachother and only the server is accessible from the outside the network.
What I need HELP with:
I have read around that it is possible to set a 1-1 NAT (I know where it is in the menu but have no clue what it does...) so that I can NAT a single public IP directly to a single private IP (in our case the server). But please, How do I do that? Or maybe an alternative?
