850 series urgent help

[barney]

Hello all, newbie here.
Got an 850 here that i can ping from any pc on the internal network and which connects to the RAS at ISP. The problem is the ISP can't ping the router and we can't ping anything externally, so no internet access.
I'm a cisco novice so please go gently

Config is below

!This is the running config of the router: 192.168.2.1

Welcome barney, hopefully we can help you. First thing though, remove the sensitive bits from the posted config - e.g. external ip, ppp user/password, domain, etc.

Next, try removing the default route that you currently have (ip route 0.0.0.0 0.0.0.0 ATM0) and replace it with a default route pointing out the dialer:

ip route 0.0.0.0 0.0.0.0 Dialer0
