RE: [pfSense Support] Firewall rules keep failing
Thanks, and yes I am applying changes. It seems to be that action (reloading the firewall rules) that causes the problem. I don't know too much about the BSD internals of PFSense but I have been using it for a while (and m0n0wall for embedded applications) and am reasonably familiar with how it is supposed to work, which is why I'm a little frustrated by this problem. I am thinking of rebuilding the system from fresh and configuring it again, it's not a very complex setup.

RE: [pfSense Support] Firewall rules keep failing
Chris Seems you may be on to something. I have removed Squid and what was a very re-producible issue doesn't _seem_ to be happening. I had thought about that but dismissed it as it was affecting ICMP/Ping, TCP/FTP and other traffic which I didn't think squid would interfere with. However now I have another problem, It's most important to have the security but squid saves us hours of time and gigs of bandwidth a day by caching updates for all the PC's that come through our workshop. Really could do with it installed and still have the intended security. I guess I could have a second PFSense box caching within the workshop segment but it shouldn't be needed.

You can easily install a dedicated squid box (not a pfSense box running squid) in your network and accomplish the same goals. Graeme Evans wrote: Chris Seems you may be on to something.
