Hi all,
We need AES so I have just tried to upgrade one of our VPN routers. After the upgrade I have about 50% of packet loss through an IPSEC tunnel. The other side is a checkpoint Firewall.
old IOS: c3640-jk9s-122-23.bin new IOS: c3640-ik9s-123-14.T7.bin
After downgrading to the old IOS, I had no more packet loss. So, the problem is related with the IOS. phase 1 and 2 are up, and I see no errors. Anybody an idea what could be the problem, or how to debug?

There are a few possible approaches.
- Try different releases - Read release notes to see if you might be hitting a known bug - Troubleshoot problem to see if it can be fixed.
If you wish to oursue the latter please set up test
clear counters
run test and after 10 minutes of loss while the loss is still occuring gather
sh proc cpu sh int ! for all relevant interfaces (inbound and outbound) sh buff sh mem (first few lines)
please send description of test and network.
