Routing between two routers with serial interface E1

Routing between two routers with serial interface E1

Hello good afternoon community, I would like to obtain some reference on a problem that I have in a network topology.
You have two routes in router 1 I have configured a call manager with two IP phones, in the second router I have configured a VPN.
Both services work fine.
router 1 has an E1 serial interface and router 2 has an E1 serial interface
My question is when I want to route traffic from router 1 to router 2 and from router 2 to router 1 through the serial interfaces of router 1 and router 2, I use the following command

IP Route 0.0.0.0 0.0.0.0 Serial0/0/1:0 on both routers.


when I ping from a terminal of router 2, I can find the phones on the side of router 1, but when I try to connect to the VPN from the WAN, it doesn't connect.
When I try to connect the VPN from the LAN if it connects correctly.

Can anyone give me any suggestions on what I'm doing wrong?
Here is the diagram.

Thanks .

Hello,

 

Its most likely you don't have a route back out to the WAN. Your R2 knows about the 192.168.0.0 network but nothing pat that out to the WAN. @MHM Cisco World is partially right in that if you are going to do static routes the take your R2 all 0's route and replace it with the 192.168.1.0 network out that interface. Then you would put your all 0's route (default route) on R2 pointing out the G0/0 interface to say all 192.168.1.0 traffic go out S0/0/1 interface. All traffic I don't know about (to include traffic from WAN) go out G0/0 to the WAN. Make sure your WAN connection also knows how to get to your networks inside.

 

If you want you can do dynamic routing with the following commands on R1 and R2:

 

conf t

router eigrp 1

network 0.0.0.0


Also on R2 you would need the default All 0's route to still point out G0/0 interface.

 

Hope that helps.
