To give RDP external mgt to servers and let users remotely access desktops I was using UPnP to forward firewall external IP address with port number that through upnp transates to internal IP and rdp port.
I.E. RDP to 22.214.171.124:50009 Firewall/UPnP 192.168.2.24:3389
I was recently told this very insecure (obviously hacker can try this port), but also told that most firewalls do not filter ports in this high of range (what is consequence of not filtering if this is the case?). I was trying to avoid managing Desktop vpn software (this is from XPpro to XP pro, or Xppro to win2003 server), and have had little luck configuring xp native vpn connection. Thanks, experts
