Below is the conig for a demonstration Remote Access Server which has PPPoE setup for broadband access via GigabitEthernet0/1 which works fine and a connection into the core network via GigabitEthernet 0/0.
We are trying to setup dial in narrowband PPP access using the modem card in EHWIC slot 0 but are having routing issues with it.
The dial in client obtains an IP address from the pool fine and knows the IP of the RAS correctly but neither can ping each other.
Below is the running config together with the output from show ip route and show line 0/0/0 and show int async 0/0/0
Can anyone please help me understand whats wrong here, it seems to be the same as the examples Ive looked at.
Thanks

To clarify I cant ping 10.3.0.14 from the RAS and I cant ping 10.3.255.254 from the client.
Below is the log from the client (a Mac using the built in Mac OS X PPP/dial up software and modem)
Modem Reliable Link Established. Modem Compression Established. Communicating at 33600 bps. Connect: ppp0 <--> /dev/cu.modem local IP address 10.3.0.14 remote IP address 10.3.255.254 Serial link appears to be disconnected. Modem hangup Connection terminated.

Same problem here, tried to setup dial in for remote access to a router via a phone line using the above method.
Modem connects fine Windows PC Received IP but cannot Ping/Connect to the Router or the Other Way round. Any idea why this is not working ?.
