NAT server problems

[mothsmoke]

Hello,

I have problems sharing my internet connection (adsl) through NAT. I have already used Internet Connection Sharing (ICS) but I heard it doesnt provide you with much options and security. So I switched to NAT and I cant make it work. (ICS is now disabled)

I configured, DHCP, DNS, setup an internal domain (as I dont have a public domain). They are working fine.

I try opening routing and remote access, install NAT/firewall, both public and private interface. I do not choose the option of DNS/DCHP allocator through NAT as I have already done through DHCP and DNS itself. Or am I doing something wrong here. I can use the internet on my server itself but cannot share it for some reason.

Help would be appreciated.

Background Info:

Small office network

Server: 1 x w2k3 - IP 192.168.0.1

clients: 2 x winxp - IP 192.168.0.2-3

Do you have two NIC in your Server?

If you do then you need to set the Wan interface to DHCP and the LAN interface to Static

then you need to configure routing between both interface

If you have one interface

Then you need another interface

If you have all this configure

Then post more information about your routing configuration

Have fun!!!

NIC? I mean I have all the 3 comps setup as a LAN (all of them have lan cards and are connected to a hub). Thats all working fine.

I think I set 2 interfaces in NAT. Private and public both.

Could you guide me or provide me some link to set a WAN interface?

NIC is the lan card, you need to have 2 on the server.

1 for the LAN, with a static IP address, and the other to your router/modem connected to the internet.

Give me more time and I will make a quick guide for you... PM me if you want it...

Yes, I got an ADSL modem and a LAN card on my server. Connected to other clients through a hub.

My LAN, file sharing is all working fine. Its just the internet connection sharing through NAT that I cant seem to do. Previously I've been using ICS and it all worked fine.

Yes I am having a static IP for my server. 192.168.0.1 and its my default gateway, dhcp, dns server as well.

Go back to ICS. It gets significantly beefed up in XPSP2, and again in Server 2003 SP2.

You can do it with one nic, but you have to assign static ip addresses and your ISP must give you a static IP (simply assign two IP to the one nic one external and one internal). Of coyrse you could also just go out and buya $40 router which would share your internet through NAT and take the overhead off of your internet server.
