The client(Client A) router is configured with
ip address 172.20.96.2 255.255.240.0
On my router(3600) I am advertising 172.20.96.0 /20 and I am routing it back to the client via the interface(s1/0) they connect to on my router.
Here is the problem. I have another client(ClientB) connected to another serial interface(2/0) on the same router this client connects to but what ppl coming from the 172.20.110.0 /24 range(Client A network) are not able to connect to that the device. They do a traceroute to the device and it times out on the Fe.
The funny is though that ppl from 172.20.96.0 - 172.20.99.255( Client A network) are able to connect to this device.
I have spoken to Client B and they are not seeing any connections hitting their firewall from the 100-110 range.
What am I missing? There is no route statement on the Client A router to say ip route (client B device)via serial0 which is the entry point into my network.
Please help? Been on this for two days now.
