Pfsense stop responding after some hours

  • Hi Experts
    I have installed pfsense 2.0.3 on an assembled system (core 2 duo, Gigabyte Motherboard with 2 GB Ram and 160GB HDD). This systems has one onboard LAN Card and 3 on PCI and PCI Express Slots, so total 4 LAN Cards.

    In my environment we have 3 ISP's so i assembled this firewall in this way.

    After installation every thing works fine but after some hours it stops responding and i am not able to figure out the problem. Can you please suggest what could be the possible cause.

    FYI: WAN has Static IP and OPT1 and OPT2 are on DHCP mode.

    waiting for your valuable suggestions.

    It what way does it 'stop responding'? No access to the webgui? No access via SSH? No console access? No replies to ping?

    Anything in the logs?

    Has this always behaved this way?


  • thanks for revrt Stephen.

    If i take out OPT1 or OPT2 (any one) then it works fine. I also noticed that these two ISPs are on DHCP and has same IP
    i think this might be the one of the cause. This week end i will change LAN IP of one of the ADSL Modem then see how it goes.

    You must have a different subnet on each interface. So if your LAN is still using (the default) you will have to change both OPT subnets to something different.
