*solved* Update to 2.3 from 2.2.6 1:1 NAT not working



  • Yesterday I updated from 2.2.6 to 2.3.

    Now no IPv4 1:1 NAT Traffic is working. Normal NAT outgoing is ok. IPv6 stack is working as expected. Only 1:1 NAT is making problems.

    Any idea what could cause this problem?

  • Using IP aliases with a CARP IP parent? See the regression noted here related to that, with info on fixing.

    "IP aliases with CARP IP parent lose their parent interface association post-upgrade"

    If not, what type of VIP?



  • Yeah you are right ip aliases on carp - i set the carp ip as parent and all is working as expected.

    thanks
