Repost of earlier question this time with the full config attached.
I been using the attached vpdn config on Cisco 837s for ages and it's always worked. However after upgrading a 837 from 12.3(7) to IOS 12.3(14) I can make a VPN connection to the router but I can only ping the router and not anything else on the remote network. If I switch back to an older IOS e.g. 12.3(7) it works, but when I switch to 12.3(14) it stops again. This is with exactly the same config file.
When I posted just the vpdn related bits of the config it was suggested that something else like a NAT rule might be causing the problem, so I've posted the full config. However note that the exact same config works fine with12.3(7) and doesn't work with 12.3(14) so if there is an error in the NATing or elsewhere it must be a subtle one.
Incidentally nothing appears in the log or as an SNMP trap.
Any ideas? This one has me baffled.
- local network is 192.168.1.0/24
- there is an IPSEC VPN that shouldn't be interfering with vpdn
- IP addresses and passwords changed to protect the innocent!
