cisco vpn client randomly disconnects with pfSense
-
My network has two gateways, one is a pfSense box that everyone uses. The other one is a TP-Link firewall essentially for tests.
Some machines inside my network need to access a VPN through the Cisco VPN client. If one of those machines is using the pfSense box as the gateway, I experience random connection drops on the VPN. If I am using the TP-Link gateway that doesn't happen.
I've tried changing the MTU in the pfSense box and that improved things a little bit but didn't really solve the problem. I also followed the guidelines for traffic shaping in pfSense and the connections still drop quite often.

The VPN is actually disconnected or traffic inside it stops?
Check for blocked traffic at that time. Check the states still exist.
Are you running Snort or Suricata? Check the alerts.Do you have multiple internal clients using the VPN client connecting to the same external server?
