Squid - server timeouts
We have a pfSense 2.1 firewall, running Squid 188.8.131.52_07. The unit has one lan, two load-balanced wan interfaces and a third enabled interface (bridged with LAN) that connects to an external VPN device.
Occasionally http connections to certain servers on the VPN connection fail with server timeout messages from Squid. We are able to ping the servers over the VPN, even though the we get HTTP time outs. If we disable/enable the VPN connected interface http connectivity is restored to the sites.
Has anyone come across this type of issue before or have any suggestions as to a possible solution.
