Something like this also works,
For Players:
- Create a Shortcut from your nwmain.exe file, found in your main NWN folder.
- Right-click on the shortcut and opt for 'properties'.
- In the Target field you should see the full path to where this file is linking.
- Type the following after the quotation mark: +connect 84.238.55.137:5121
For DM's:
All of the above.
Except the Target field is different.
After the path, type in the following:
path/nwmain.exe -dmc +connect 84.238.55.137:5121 +password [insert DM password]
You can make multiples of these for each server you play as well
