      Hello Guys!

      By the way: great work. I like pfsense - it's stable, PPTP is working, configuration is fine, Webgui intuitive.
      But the only problem i have is:
      Sometimes (once a month or something) there is no connection from LAN -> DMZ anymore. The firewall from PFSENSE won't let anything out. There's a rule allowing LAN -> DMZ: all and some Port from DMZ -> LAN. LAN ist 192.168.0.* and DMZ is 192.168.100.*.

      To make it work again i have to "refresh" the Firewallsettings (deactivete a rule, activate it again and "Apply Settings"). After that it work's again for some weeks. Any hints?

        Version? Hardware?

        If you visit the firewall tab in the logs do you see anything blocked?
        Any other entries in the system-logs that indicate a problem?

        We do what we must, because we can.

          Version: 1.0.1
          Hardware: dmesg is too much i think :-) Normal PC with 3x 1GBit ETH, CPU 3.5GhZ, 1GB RAM

          Logs has been okay. The next time the problem occurs I'll take a closer look.

            I can't see anything unusual within the logfiles. After reloading the firewall (deactivate/active a rule and "apply settings") it work's again. Any ideas?

              what are you trying that doesn't work?  i.e. is it just one thing that stops, like HTTP maybe, or do pings not work, or does everything stop, or?  You can still get from LAN -> Internet and DMZ -> Internet when this happens?

              1.0.1 isn't the recommended version anymore. I would definitely recommend upgrading to 1.2rc2 since you're having problems.

                Nothing is working, not even ping LAN -> DMZ. WAN -> DMZ is working.

                So i should upgrade you think? I'm unsure which package to use from ftp://reflection.ncsa.uiuc.edu/pub/pfSense/updates :-)
                This one using the WEB Gui Upgrade function? pfSense-Full-And-Embedded-Update-1.2-BETA-2.tgz? Never upgraded before…
