I have a rule on a stormshield performing NAT on both the source and the destination address. It is done very simply in one rule. Example :
--Before translation-- --After translation-- Source Destination Port Source Destination Port server1 FW_WAN_interface 7474 FW_LAN_interface computer1 7474
I want to add the same rule in a pfsense. I searched a bit and the only way I found is to do an inbound and an outbound separatly.
I have a few questions on how to do it :
Does pfsense read the inbound rule before the outbond rule when the traffic come from the WAN to the LAN ?
If so, will I have to adapt the second rule considering the traffic modified by the first rule ?
