Windows 2000 RRAS - Configuration problems

Hi, I've got a box running Windows 2000 AS, I'm trying to use RRAS to route between our two domains ( and and provide internet connectivity via the firewall (

The Windows Box has three network cards:

From any of the domains I can ping traffic throughout, eg to, I can ping the firewalls internal address, from anywhere on the LAN, but the only place I can ping the External firewall address is from the Windows Box, on all the other machines tracert shows the route ending at the Windows box. eg or

This is obviously a routing problem with the Windows box, it is configured with NAT enabled. Below is the routing table.

Any help anyone can give me with this is much appreciated, using Linux is NOT an option and I would prefer not to use a thrid party application.

Many thanks

Chris Moon

I think the problem may be in the first line.  You show a default route with a gateway of, but it says to get there using the interface  I don't think this will work very well.  Try deleting this line using the route delete command and see what happens.

Obviously you have configured 2 NICs with a default gateway ( and And your default gateway is wrong.
There can only be one default gateway, which you should set to NIC as

Depending on your firewall config you will not be able to ping the external firewall address (a properly configured firewall dismisses ICMP echo requests, at least at the external address), but connectivity should be ok.

I solved the problem, for some reason none of the routing worked when the box was initially started up, however once it was logged in, restarting both the RRAS services and Disabling/Enabling all the network cards starts the service flawlessly.
