Point to Point E1 Cisco Config with Static routes - Urgnet help!!!
I have quite a simple point to point configuration
PC1-------172.18.128.0/24-
Router1:
FA0/0 172.18.128.77
Ser0/1/0 10.100.5.1
ip route 10.23.1.0/24 via 10.100.5.2
Router2:
FA0/0 10.23.1.9
Ser0/1/0 10.100.5.2
ip route 172.18.128.0/24 via 10.100.5.1
PC1=172.18.128.80 (static)
PC2-=10.23.1.10 (static)
Router1 can ping its Ethernet and serial IPs
Router1 can ping Router2 serial and ethernet IPs
Router2 can ping its Ethernet and serial IPs
Router2 can ping Router1 serial and ethernet IPs
PC1 can ping Router1 on Ethernet (172.18.128.77)
PC2 can ping Router2 on Ethernet (10.23.1.9)
Neither PC can ping accross the routers to each other? Whats missing?

What are the PC's default gateway? The router with the E1? or something else? Do the PC's have the Windows Firewall running?
What you have looks ok, What I probably would have done is an ip route 10.23.1.0 255.255.255.0 serial 0/1/0 and the same back the other way on router2
Can you do a sh run on both of those devices and post it?
Have you tried to ping the outside ip address(10.100.5.2) of router2? The same with pc2
Do you have cli access to the routers? If so I would ping the outside ip of router2 and source it with the inside ip of routera, Do you get a reply?
It definatly seems like a routing issue. As a side note I would use a /30 address between a point to point.
Also are you using a routing protocol?

no routing protocols - just static routes.
PCs can only pin Routers respective ethernet IP and no further

What is 172.18.128.1? You will have to add a route on that device pointing to your remote network 10.23.1.0/24 and vice versa on 10.23.1.1

I forgot, Just make sure you mirror the configuration on pcb default gateway, Such as ip route 172.18.128.0 255.255.255.0 10.23.1.9

ok so the issue is not with the routing on the routers, was simply the DG of the PCs/server?
Yes, the PC's weren't sending traffic to the routers (the problem). The router config is fine.

Thanks guys.
I kinda would argue that it was the default gateway, You shouldn't have to have it unless you really want to. That is what a router is for and I would add the route on the pc or on your default gateway.
