Re: Help troubleshooting Hairpin NAT

Just in case this will help someone else with roughly the same config as me, here was my resolution;

firewall modify SOURCE_ROUTE_2255
 rule 10 {
     description "Hairpin NAT exclusion"
     destination {
         address 10.100.0.0/16
     }
     modify {
         table main
     }
     source {
         address 10.100.0.0/16
     }
 }
 rule 20 {
     action modify
     description "Traffic outbound on Eth6 Swiftway"
     modify {
         table 6
     }
     source {
         group {
             address-group Outbound_Eth6
         }
     }
 }
 rule 30 {
     action modify
     description "Traffic outbound on Eth7 AtlanticMetro"
     modify {
         table 7
     }
     source {
         group {
             address-group Outbound_Eth7
         }
     }
 }
 rule 40 {
     action modify
     description "Traffic outbound on default table"
     modify {
         table main
     }
     source {
         address 10.100.255.0/24
     }
 }

 service nat rule 1
