Port Forwarding works for one IP but not another



  • I just installed my pfSense box and I am trying to set up port forwarding, but perhaps missed a step in my configuration.

    The IP address on my external port is .85 and if I set up a route in Port Forwarding that goes to .85 then it comes through fine.  I, however, want to set a port forward on .84 and when I follow the same pattern in Port Forwarding everything works.  However, I am not able to get to RDP through .84.  What additional configuration do I need to do so that .84 is reachable through pfSense?



  • Do you have a virtual IP defined for .84 on WAN?

    so you want to forward 3389 to your internal IP x.x.x.85 and also at the same time to x.x.x.84 ??

    Yeah how would that work.

    Lets say you have public IP 1.2.3.4 and private IPs 192.168.1.85 and 192.168.1.84

    So you forward port 3389 to 3389 ip.85 and you foreward 3390 to 3389 ip.84

    If you want to connect to the .85 box from the outside you hit your 1.2.3.4:3389 if you want to go to the .84 box you hit 1.2.3.4:3390

    All of that being said - opening up RDP to the public internet is a BAD idea!!!!  If you want to rdp to your machines while not on your network - vpn into your network, then rdp..

    I can't tell if ".85" and ".84" are public or private IPs. You need to post more information on your setup and what you are trying to achieve.
