Before I open a TAC case, I tought I'd bounce this one off everyone.
I am experiencing an issue which occurs with IOS 15.0M and which does not occur with IOS 12.4(24)T1. I have verified this by reverting to 12.4 on a production router where I experienced the issue after upgrading. I can reproduce the issue freely in a test environment. I have experienced this on both 2800 series and 871 routers.
When an ASA (ver 8.2(1)) or PIX (ver. 6.3(5)) operating as an Easy VPN client in network extension mode connects to a router running IOS 15 with a traditional crypto map-based configuration acting as an Easy VPN server, traffic can pass to and from the client site and the site to which the VPN session is connected, but cannot pass beyond the router's site to other sites on the network, even though all routing entries appear to be identical to that under 12.4.
The problem occurs regardless of whether a full or split tunnel is being used.
(In this case EIGRP was being used between the router sites, but the symptoms persist even with static entries.)
If I can duplicate this, surely someone else can as well.
