      My config

      Two hosts 1&2, host 2 located on LAN has a virtual IP in the DMZ. NAT 1:1 enabled between IP:A and IP:C

      My goal: to block traffic IP:B -> IP:C, but allow IP:B -> IP:A

      I beleive that the NAT 1:1 translation is applied BEFORE the firewall rules. So in fact the rule "allow IP:B -> IP:A" has no effect AND the rule "block IP:B -> IP:C" also blocks traffic IP:B -> IP:A.

      How can we workaround this ?
