1721 VPN Bundle, does not work unless!

[BAsh12]

We have a 1760VPN Bundle in the middle and 2 x 1721 bundles. All have additional ISDN bri cards. When the VPN is set up, we can ping one, at the most twice to the other side, after that nothing, at all.

We put the same config on to an 837 router, when I say the same config, I mean, the same, the only change of course is the f0 interface instead of e0. Works perfectly.

So, we have spken to Cisco, no use, we are under a hell of a lot of pressure to get this working.

The answer? Take the AIM card out, perfect.

IOS? We have tried them all, literraly. No change. We know the version we have now is ok for all the features we are running, from the Cisco web site.

My question is, do we have to make a change to the config so that we can use the AIM? I think not, it should be automatic. So why the hell will it not work?

It may be a bad VPN module. The 1700 routers do not have an AIM card it is a VPN module. There is no special configuration needed to make it work so if you remove the module and the VPN works then I would say you have a damage VPN module.
