AIM VPN Module

I have a 3725 running 12.2(8) with two VPNs one a tunnel to a 2650 and one dynamic VPN's coming in from remote users running vpn client 4.0 both used 3des encryption. I added a AIM-VPN\EPII hardware encryption module and loaded IOS 12.3 the VPN tunnel carried on working fine but the vpn Clients stopped. I put ISAKMP debugging on and i got a message that pointed towards the clients having the wrong encryption which should be AES, i thought the Hardware module didn't change any settings, has anyone had any experience with these.


Re: AIM VPN Module

As far as my knowledge goes, the 3725 supports the AIM-VPN EPII hardware encryption module with IOS 12.3. However, there is a bug that has been filed for an issue with high CPU utilization with AES and EP-II module for 12.3(1) and 3700 router. You could check if this relates to your issue, although I believe that the hardware module does not change any settings until a configuration change has been made. The bug id is CSCeb31614 .
