SSL traffic blocked after some time
I used to have a squid proxy connected to an internal interface of pfsense (version 1.2.3) and it worked fine for months. Due to the IPv6 support now I'm testing it with pfsense 2.1 and I have encountered the following problem:
When pfsense 2.1 starts, everything works as is expected, but later, pfsense start to block ssl traffic from proxy server to outside (the http traffic continues working). If you restart pfsense the https traffic start passing again from proxy server until the problem recurs (hours later).
There is some option or parameter I have to activate or to tune at 2.x versions related to ssl traffic ?
Thanks in advance
