Before we get started directly with Router configuration, let's know little information about Port Forwarding which also known as PAT (Port Address Translation). In PAT we'll use one public ip or more with different port numbers like, if you want to ssh your server, you'll be router send all the traffic on that particular port to different ip and the LAN, in the same way all the web traffic to some other ip on LAN, and so on, in this case we are using only one IP but ports are different.

When it comes to NAT, you are telling your router to that what ever traffic comes for the ip 10.10.10.1 should be transferred or routed to 192.168.85.1 which is a server on your LAN. In the same way traffic for the ip 10.10.10.2 to 192.168.85.85.2, this is also called as One to One NAT.

Now we'll see configuring PAT on our Cisco RV042 Dual Wan Port VPN Router. In this post i'll configure for vnc which uses 5803.




After you are done with last step, don't forget to click save at the bottom of the page. That's all you configured.

Now open vnc viewer and try to connect. Only difference is use public ip instead of private ip.


good luck.
