      Hello,

      I have problem with Gateway packet Loss since I configured CARP in my environment.

      I have such configuration:

      • 1 WAN Fiber with single external IP
      • 1 WAN DSL with 3 external IP ideally for CARP, but this link is slow.

      I configured it in such way:

      • WAN Links are connected to switch with differents VLANs:
        – fiber WAN with VLAN13
        -- DSL WAN with VLAN14.

      This is how I see that:

      I have configured gateways, gateways groups with those WAN's so it will be load balanced. It was working without carp flawless (I think it is still working).

      –- Now about CARP
      I've configured CARP according to pfSense WIKI and it looks that everything works as expected.
      I have setup NAT my WAN to my gateway address so it can connect to Internet and everything is working...
      Only problem is that since than I have packet loss at ~20% level with both providers and I really don't think that both providers would failed.

      Where can I look for some bugs with config; I don't have any CARP logs, only info that some gateway is down...

      Thank you for any help :)

        It seems, that one provider had failed and it is working now.
        Unfotunately some users have "blackouts" from time to time for about ~5 minutes.
        Do you think it could be problem with outbound NAT or where should I look?
