[edit] Descriptioon
This script will reroute all LAN->WAN traffic that's normally blocked(router loopback prevention). It solves the issue where only LAN-users OR WAN-users can connect, but not both. Use it on every LAN-client that's trying to connect to a LAN-UGAI. External ip in your ./Region/Region.xml should be your WAN-ip.
