I am running 3 ASA5505s with firmware version 8.2(3) and ASDM version 6.3(4)53. I have a bonded T1 in location and single T1s in the other two locations. I am running L2L tunnels between the three sites and I have been experiencing tunnel drops without reconnection. After over a week of 5 different Tier 3 Cisco engineers, I am still dropping but I am getting the tunnels back after about 5 minutes. This is apparently happening during the rekey process. We have tried everything including disconnecting one of the T1s in our home office location. I am a wits end and need some additional advice. I have read that the 8.0 version of the firmware was not as buggy as the 8.2. Has anyone tried rolling back the firmware? I also heard that there is an 8.3 version but it requires additional memory and has major changes to NAT. I am on the brink of tossing the darn products and starting again from scratch.
Suggestions?
