Can someone help me with this? Should be simple. I would like to configure an NT 4.0 Server with DHCP enabled and with two NICs to act as a router between my private LAN (10.10.13.XX) and the internet. Obviously, I have configured DHCP with Router 003 option and specified the IP of the router, which in this case is the server, with IP address 10.10.13.21 When I query each workstation with ipconfig /all I find that DFG address is being recognized, but the clients will not route to the internet using Internet Explorer 6. What am I missing? I know it must be something simple, but I've never don this before and hey, a match is confusing if you've never used one before. Thanks! I appreciate any and all assistance.

If you like you could email me directly at eansor@yahoo.com That way I can pick it up anywhere. Thanks!

1. Right click on Netwk Neghborhood/Properties.
2. Choose tcp/ip properties
3. go to routing tab
4. Check box that says enable IP Forwarding.

This will enable routing between the networks.

Ok with that in mind....

This would be fine if both netwks were pvt or both were public.

But Your pvt netwk still will not be able to get on the net.

Why? The 10.0.0.0/8 class is a pvt IP range and is not routable across the net.

You will need a proxy for that.

You can route between a 172.16.0.0/16 netwk and a 10.0.0.0/8 netwk without any problem. But try to get a 10.x.x.x host out to the net and you will have problems. That is where the proxy comes in.

The good news is, You can get 2K srvr and use it to NAT the connection. It is fairly straight forward.

For NT4, you will need proxy srvr 2.0 in order to accomplish your goal.

Or set up a linux box.

As LordInfidel says, it will be easier and cheaper to set up a Linux proxy box.

You didn't mention if you are actually accommodating the potential user count for your pvt net config.

As a side note, if you are a bonafide developer :-) tic, youcan get MS's action pack (loads of MS not for resale OS?s and software for really cheap.)

$299 for approx $10k of sftw.

Caveat... you must meet their criteria...

Perhaps an avenue to go Win2k

Good Luck
