Cisco 871 connection issues

Hi Everybody,

I'm stuck about a week in a troubleshoot. I have a Network that looks like the image1. This network is a mess and I'm still trying to understand how does it work.

Topology El Salvador.png

the network has two routers with two different ISPs. Both routers has a VPN connection established with the Datacenter. One VPN (Router 2) is used to route the traffic from the voice VLAN to the Datacenter. The other VPN (Router 1) is used to route the traffic from the Data VLAN to the Datacenter (don't ask why because I don't have a clue either)

The issues is I have this server that has the IP address 192.168.65.200 and the default gateway 192.168.65.2 (Router 2) also the server has two Persistent Routes configured:

Network Address      Netmask          Gateway Address  Metric

192.168.44.0            255.255.255.0  192.168.65.1          1

192.168.47.0            255.255.255.0  192.168.65.1          1

This means that all the traffic to the Datacenter will be sent using the Router 1 and the traffic to internet using the Router 2.

I have something weird with the Router 2, it starts to route the traffic to internet I put a continous ping from the server to for example www.google.com and it replies. Suddenly it stops to reply. when I go to the server and ping the Router IP it replies (192.168.65.2) the Router Public IP replies, But the Router default route does not (When I test form the server).

When I go to the Router 2 and try to ping www.google.com it is successful. I can ping the default route IP and it is successful I also can ping google using the LAN interface as the source IP:

ping 74.125.67.103 source 192.168.65.2

I need help because there is something with the router, but I don't really know what to Debug.

Thanks

Jose
