I am using an RV160 and I want to do 1:1 NAT between one address on the private and public side of the router. I want to initiate a conversation with the device on the private side from any device on the public side. The problem is that I can't set the default gateway on any device. How do I configure IP Masquerading on the RV160 so that when it communicates with the device on the private side it looks like it is the RV160?
