UFW OpenSim configuration

1)Create a Launcher with opposite clicking the Desktop & selecting "Create Launcher"

2)Name it GKSudo Launcher & Insert the command: gksu "gnome-open %u"

3)Open GKSudo Launcher & navigate to the file folder /etc/ufw/applications.d/

4)Create New Document with the example information:

[OpenSim Listener]
title=OpenSim Listener (OpenSim, Listener)
description=Opensimulator, 3D application server
ports=9000/tcp

[OpenSim Regions]
title=OpenSim Regions (OpenSim, Regions)
description=Opensimulator, 3D application server
ports=9000,9001,9002,9003/udp

5)Open your Terminal(Consolar) & type:~$ sudo ufw restart

6)Type:~$ sudo ufw status & you should get a message similar:

Status: active

If you are still experiencing problems with your Grid access, it pertains nmap, which is more complicated than simply a Modem Port Forwarding issue, and though Port Forwarding is pertinent within nmap, the "n" in nmap references "Network". Haha
