Having an issue with 2 RV042 which are setup with a Gateway to Gateway IPSec Tunnel. Cannot get a one to one nat working for some reason. Can get port forwarding to work but need to set access to an inside address on a different public address. Do not want to use the public address on the router. Want to do one to one nat for our mail server.... Any issues that anyone knows of? running 188.8.131.52 code. Didn't want to update firmware if I did need to but if it will fix the one to one nat the I will.
