This works perfectly well if done correctly. Please show your configuration - just two sentences stating "it doesn't work" is too little information to help you.Essentially you need to- set up 2 WAN ports and gateways- set up 2 LAN ports without gateways- set NAT to manual- create two outbound NAT rules - one for each WAN port with one of the LAN networks as source- create two permit rules - one for each LAN ports, explicitly setting the desired WAN gatewayHTH,Patrick
