RV042G One-to-One NAT

I have just installed an RV042G router.

I have one subnet listed as the primary at 172.31.255.0/24.

I have a second subnet on 172.16.0.0/16.

I have One-to-One NAT set up for two computers on the first primary subnet.

I am trying to set up One-to-One NAT for two computers on the second subnet. How can I do this?

RV042G One-to-One NAT

Hi Dean,

To be able to do this you will have to acquire a range of Public ip addresses from your ISP.  If you have a public ip range,  then use the one thats  not being used for WAN or your primary (172.31.X.X). This would be mapped the same way your Primary is setup. Add to the one to one NAT list. Use proper public subnet mask. Include the Range lengh of public ip addresses provided by ISP. Here's a link on of instructions and screenshots on how to setup one to one nat.

Hope this helps!

RV042G One-to-One NAT

I have a range of public IP addresses. Here is what happens when I try to add the second One-to-One NAT.

While I am fairly certain the router software could handle the mapping, the HTML interface won't permit it.

It is not accepting the other subnet which is shown in this image.
