W2k router connecting, but not routing

I have 2 W2k servers configured as demand-dial routers using analog modems. Server1 has a single modem and is configured with an interface to connect to Server2 which has multiple modem ports. Server1 is connecting successfully on its own and has successfully replicated AD. Server1 always connects on the same port.

While the 2 servers are talking together well, I can't establish any connectivity between the clients on the 2 subnets. I'm not finding any errors in the System logs. Do you know what I'm doing wrong? Feel free to contact me directly.

Thanks,

Can you give us some more detailed routing info? Are the two servers on the same or different subnets? What are the subnet(s), masks and default gateways? What are the clients using as their default gateway? What do the servers' routing tables look like? Is there Internet connectivity either on one or both of these servers or somewhere else on the LAN? Without a lot more detailed info I don't think anyone's going to be able to give you much help.

You can try to add a fixed route back from the server to the client subnet. You should use the route add command to your external IP address interface. Most often the gateway is defined correctly, but the route back is not defined, and you have to define it in case of RRAS.

Route Add was the whole problem. I thought that was the important piece, too...it's not. You gotta configure the routes *within* the RRAS MMC in the Static Routes dialog. All the routing was correct...it started working when I configured the routes inside the RRAS service as opposed to the server routing table.

However, when the server later disconnected and then re-created the demand-dial connection, the routing stopped working. I removed the routes in RRAS, restarted the service, andre-created the same routes in RRAS...and it's working again (buggy?) My first experience w/ RRAS demand-dial routing: it's a beating.
