Can't get to proxy server through routers.

Hi,
I have 2 2507 cisco routers connected with a back to back serial cable.
I have 2 networks, 10.10.10.0 and 192.168.1.0
The serial port ip's are 75.75.75.1 and 75.75.75.2
Workstations on the 192. side can log on to a server on the 10. side. All computers on both sides can ping each other.
I have a proxy server (10.10.10.4) with a dial up internet connection. All computers on the 10. side can get to the internet through the proxy server. When a computer on the 192. side tries, the dial up window will pop up on the proxy server and make the connection but the computers on the 192. side never get to the inetenet.
I thought it might be a DNS problem but I have the same info on all computers on both sides and the ones on the 10. side works fine.
Do you think it is a router problem or something else?
Thanks.

Looks like a routing problem

Do you have a default route on the 192.168.1.0 router that points to the 10.10.10.0 router?
ip route 0.0.0.0  0.0.0.0  <serial IP of 10.10.10.0>

And on the 10.10.10.0 router you should have defult route pointing to Proxy server
ip route 0.0.0.0  0.0.0.0  10.10.10.4

Also, are the browsers configured with the IP of proxy server?

I tried adding static routes but I did it wrong. You will notice I have 2 ip routes on router1. Can anyone tell me how to get rid of a static route?
Thanks

If you want to get rid of this:
ip route 75.75.75.0 255.255.255.0 10.10.10.4

simply use "no" in front of it

router(config)#no ip route 75.75.75.0 255.255.255.0 10.10.10.4

You might want to add to router 1:
ip route 192.168.1.0 255.255.255.0 75.75.75.2


Is your RIP working?

Does your proxy server have a route to 192.168.1.x subnet?
Try adding a static route on the server:

C:\>route add 192.168.1.0 mask 255.255.255.0 10.10.10.1

Hi,
After I added a static route to the server I removed all static routes from the routers and it still worked.
The server is Windows 98 running FreeProxy.
Now I need to see if there is a way to keep from dropping the static route when the server is rebooted.
But you've got me on the right track!!
Thanks

To make the route change permanent, just use a "-p" flag
c:\>route add -p 192.168.1.0 mask 255.255.255.0 10.10.10.1
