Ipsec to asa 5545x drops every few minutes
Old setup: Dell Optiplex GX280 running pfsense 2.1.
Was exhausting the RAM which was causing performance problems. So I moved to:
Dell T710 (running vmware) with pfsense 2.2.2 (running as a VM)
I did a backup of the 2.1 and restored to the 2.2.2
I have an ipsec tunnel to an ASA 5545x which has been flawless for over a year on the old hardware/software. After the move/upgrade the tunnel drops every 5 minutes. ASA is reporting that pfsense is dropping its SA due to DPD timeout. DPD is not enabled on either side of the tunnel.
EDIT: old system was 32 bit, new system is 64 bit
Can you post debugging logs of both sides?
