      johnpoz said in How to block RDP access in 1:1 NAT setup:

      if you only need http and https, just forward those

      Or at least block all the other ports on the 1:1 NAT, because otherwise you're opening up file sharing, RPC, whatever else is listening on Windows on a LAN. Probably easiest to add a rule to allow HTTP/HTTPS and block the rest.

      Pre-2.7.2/23.09: Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
      When upgrading, allow 10-15 minutes to restart, or more depending on packages and device speed.

        @teamits Yes however "1:1 NAT maps all the external ports on that IP to the internal IP but you must still have firewall rules to allow the traffic to reach the local server."

          Hello!

          Port 6665 for remote access to your network seems odd, not because IRC is odd, but because that port has been so badly abused.

          You might want to pick a "safer" port, unless that is not your intent...

              Security though obscurity is not security... Opening up rdp to the public internet no matter what port is a BAD idea!!! If you want to rdp to this box, then vpn in and then do it.
