Here is a finding for those who have upgraded or purchased a new 2621XM with memory above 128MB. I have verified that the advanced Security IOS version 12.3(11T3), will crashdump and reload, when attempting to VPN from a client inside the network to a VPN server outside, if your router memory exceeds 128MB. Hopefully, the programmers know of this issue and are trying to figure out how to fix it. Once the router is taken down to 128MB this same VPN action succeeds. If anyone else has seen this and knows of a work around other than removing any memory above 128MB, please reply to this posting.
