This is a feature request for the Linksys RV series Routers. Currently, it appears that the Cisco/Linksys RV042, RV082, and RV016 only support port forwarding and 1-to-1 Nat. One item that I find very helpful with customers is port forwarding with port translation. I am requesting that this feature be included with a future firmware relase for these RV series routers.
Here is an example of the request.
Take an incoming service request on a TCP or UDP destination port and forward it to an internal IP on a different TCP or UDP port. For example, customer A wants to allow different machines on the internal network to receive Windows RDP connections inbound. To make PC maintenance identical between the internal machines, the customer does not want to change the listening port for RDP on the individual PC workstations through the Windows Registry. The customer also does not want to dedicate separate IP's to each machine in a 1-to-1 NAT setup. The only option is to have remote connections to each of these PC's to use a different destination port. So, for example, PC one could be reached on TCP port 5151, PC two on TCP port 5152, and PC three on port 5153. This requres a firewall that is able to translate each of these connection requests to a different internal IP on the default RDP port (TCP 3389). So, the following setup is required:
Port Forwarding with Port Translation:
Router External IP on TCP port 5151 ---> forwarded to PC One's internal IP on TCP 3389
Router External IP on TCP port 5152 ---> forwarded to PC Two's internal IP on TCP 3389
Router External IP on TCP port 5153 ---> forwarded to PC Three's internal IP on TCP 3389
There are several comparable "small business" class router competitors to the RV042, RV082, and RV016 that will perform this port forwarding with port translation process without incident. Unfortunately, these Cisco/Linksys small business routers will not accomplish this task currently.
Please implement this feature in a future firmware release.
