RV042 using wrong WAN address for protocol binding


I have a RV042 that is setup with a Dual WAN configuration.

I've forced VOIP traffic out WAN1 and web traffic out WAN2 using protocol binding.

The problem I'm having is that the VOIP traffic being forced out WAN1 has WAN2's IP address on the NATed packets.

How can I fix this?

Hi jlamanna1,Please make sure

Hi jlamanna1,

Please make sure you have the latest firmware :

Here is the link :

I want to verify the configuration the protocol binding should be configured as following : 

for voice over IP we need to have SIP and RTP port going through WAN 1

Source address from "ip range of the phones --- last phone IP"

Protocol SIP (5060) this port can be changed we need to check with ISP or if you have the information usually from 5060-5080

Destination " -"

choose WAN 1

 - same for RTP traffic and port for RTP need to be checked with your ISP 

- Ensure also all the phone has gateway the RV042 in case you have another Router in your network 


If still not working for you  please share with us the configuration on RV042 Protocol binding section and Network detection
