How to relay traffic coming in over two public IP's to two separate local addresses

Hi Guys,

I have an RV042 Cisco router with one incoming WAN fibre connection from the ISP.

The ISP is providing 2 x public IP's.

I'd like to map each of these IP's to an internal network address 192.168.1.x
For example:
154.155.177.40 to 192.168.1.3
154.155.177.41 to 192.168.1.4

I've setup port forwarding and is working fine, but traffic for the same protocol will now be coming in on the two public IP's, thus port forwarding won't suffice.

I'd like to receive the incoming traffic on the two local addresses respectively.

Thanks Matt,

So in essence I don't need the "port forwarding" any more?
It doesn't make sense having both specified.

Which will take preference?

I believe the port forwarding will take precedence. This allows you to map a static NAT, then override just specific ports if required.

Make sure to implement access lists to only allow the port you want forwarded through.

The other solution which works on any router is to have different public ports for the routing you want. Forward port 8080 on the WAN to port 80 on 192.168.1.4, for example, and have clients access http://<public-ip-2>:8080 to access.
