Oups, like always i half read posts :P
To access a client on a LAN thru a server connected to internet, you can use NAT or VPN but ICS is not the solution (ICS is only a light version of NAT afterall). VPN is not a valuable solution to run an EQEmu server, so you will need to use NAT.
To use NAT, you can :
- Buy a NAT Router
- Install NAT protocol in your network
In your LootEditor, you have call your icon folder "icones" so i will think your are french, here the link to install/config NAT.
First link is for W2K, it work, i used it like 2 years ago (Used to run a FTP server on LAN PC), i have never tested it under WinXP but it should work, as WinXP is only an eye-candy version of W2K.

If you dont mind additionnal softs that run in background, you can install Winroute and config "
Mapping TCP".
