I'm trying to setup an ISDN Connection between a cisco 801 router and a 3640 router. The 3640 router has a 4 port ISDN WIC which has previously been successfully configured to accept a connection from a 700 series router.

The probelm I have is that from the 3640_LAN I can ping the 801 router, but nothing beyond it. The 801 router can ping everything beyond the 3640. The IOS configurations are


801.

Many thanks for any help.

Brandon,

IMHO the problem is with the routing statement on the 801
network 10.0.0.0

The mask for your eth0 port is not for the same network!

Have a look at this and see if it helps

Just taken a look, the statement on the 801 is

ip route 0.0.0.0 0.0.0.0 dialer1

My understanding was that this statement would forward all ip requests through the dialer. There it shouldn't need the same subnet mask.

Please correct me if I have the statement incorrect.
