NAT problem

Hi guys,

I am trying to set up NAT on a windows 2003 server. I got DHCP and everything working. My clients are able to grab their IPs from the server.

This is the config of my server.
1.) one NIC connecting to ADSL using PPPoE.
2.) another NIC connecting to the LAN.

i have set up Routing and remote access.

I have tried using Internet connection sharing, and it works perfectly. However, when i try to set up NAT, it doesn't work anymore. Please help

THANKS in advance!!

I don't think I'd set up NAT in that way ... I'd keep my life simple and use the internet-connection sharing as follows:
1. NIC connecting to ADSL, use DHCP or assigned public IP address
2. NIC connecting to LAN, use private IP address on a private ip range - 10.x.x.x, 192.168.x.x, etc..

In addition if I really wanted to add NAT and I could also have a physical firewall between the ADSL device and the server NIC, I would go that route and use NAT on the firewall / router. But I'd also put the Server NIC connecting to the firewall on a different private IP net than the LAN NIC and keep ICS active.

thanks a lot for the reply.

what's the difference between ICS and NAT ? In what situation would i use NAT and ICS ? I read some books on this topic. It says for large network, it would be better to use NAT instead of ICS.

COOL..i think i will heed your advice and put a hardware firewall in front of my server. (i guess it would be quite dangerous to expose my server directly to the internet). I will try that out and tell you about the result. Thanks!
