    I have multiple servers behind a rv042.
    I would like to open the ssh port to each of these servers by mapping an external port to the internal ip:port of each server.

    Looking at the port forwarding screen on the rv042 1.3.6 i am able to map an external port only to the same port number on the internal side using a service definition. This seems weird. Is there any way I can do the following

    Ext port 7722->
    Ext port 8822->

    From what i am getting i think you might want to try port triggering or look around in that for a bit.

    Port forwarding in general with RV0x series

    You can definately forward different external to internal ports on the RV series.

    When you want to use the same external and internal port, use port forwarding, if you want to use different external to internal port, use UPnP

    Do the following for different ext and int:

    NOTE: You do NOT have to enable UPnP function, leave it on no(unless you want it)

    1. go to the UPnP section
    2. click on service management
    3. create your service with different external and internal ports(add to list then save when you are done)
    4. select it from the drop down menu
    5. put the IP of the machine you want to have the internal port connect to
    6. select enable
    7. Add to list
    8. save settings

    Next Step: Access Rules in firewall section
    9. next you need to setup access rules to allow whatever IP to access the external port you identified(by default it is not allowed)

    And your done! Its that easy. I dont know why they dont do it on the port forwarding section though.

    Same here!

    Just got hold of an RV082 coming from a Draytek background and noticed exactly the same thing.

    On a draytek, you can for example forward port 80 incoming from the WAN, to port 8080 on the LAN for example.

    Not a deal breaker as such, but would be quite useful.
