SOLVED! All NAT Traffic is blocked after upgrade + restore



  • I backed up my config, created a new installation using ISO 31.Dec.2010 an restored my config. Everything looks and works fine, but all my NAT traffic is blocked by firewall (shown in firewall log as "BLOCK TCP:s").

    I can diagnostic/ping to wan successfully and ICMP packets are NATed/replied fine through pfsense.

    Whatever rule I add (even "Easy rules" untouched), nothing helps.

    One more test: Factory defaults, IPs, DNS, Default GW setup: NAT works perfectly. I restore my config again: Argh - all connections are blocked again.

    And I'd really like to restore my settings, because I have a lot of OpenVPN clients & servers, cetificates etc. there.

    What can I do?

    Here a part of my firewall log (sorry, forum didn't make it possible to upload screenshot)

    Then I figured out a little bit more:
    It looks, as if I set up all my (auto generated) rules as "block" instead of "pass"… If I change the not working NAT firewall rule from "Pass" to "Reject", I can feel the immediate reject, so my rules seems to stay a little bit functional...



  • Argh, I'm an idiot! I added a reject rule at "Floating", but this is maybe stronger than my WAN/LAN pass rules! And I did only figure that out by clicking on the red "X", that opens a message, which rule made the reject. And this I only figured out after searching the web for a long time…
