Router is not routing the traffic to the Internet

Hi Experts:

I have a Cisco router that has the line:
ip route 0.0.0.0 0.0.0.0 10.3.1.252

There are certain sites that the router can not enroute properly, and I have to "manually" write the Static IP route to that URL.  For instance, if I want to a site like www.travelsite1.com  and I can not ping it, I add the static route and it works.

WHY ?

Here is a portion of the router configuration:
--------------------

router rip
 network 128.300.0.0
!
no ip classless
ip route 0.0.0.0 0.0.0.0 10.3.1.252
ip route 10.0.1.0 255.255.255.0 128.300.123.1
ip route 10.0.4.0 255.255.255.0 128.300.123.1
ip route 10.0.6.0 255.255.255.0 128.300.123.1
ip route 10.0.7.0 255.255.255.0 128.300.123.1
ip route 10.2.0.0 255.255.0.0 128.300.123.1
ip route 10.3.1.0 255.255.255.0 10.3.1.2
ip route 10.4.1.0 255.255.255.0 10.3.1.253

It would help to know a little more about the topology. Your default route points to a private IP address while you have some static routes for private IP networks that point to a public IP address.

Can you provide a topology map that shows your path to the internet?

The 10.3.1.252 is the firewall.

I am forcing everybody to go thru the firewall. In this way, I am closing the Port 80 and allowing only the Proxy server to go the Internet.

So I now, it seems complicated but is not.

10.3.1.252 is the firewall
10.3.1.253 is a VPN box that is doing nothing but route. It is acting as a gateway
128.300.123.1  is a Frame relay connection that allow us access to some resources

I'm seeing a bunch of routes in 69/8.  Any chance you have an interface on this router in 69/8 and have "no ip classless" in your config?  If so, stick 'ip classless' in there, remove the routes, and let us know how that works.

IP Classless worked.

Thanks PJ
