Re: connection to remote computer
The changes that you would make are done in your router.
Did you configure it for port forwarding already?
If so, which ports did you forward?
If you have set up port forwarding then the all of the user passwords should be changed from the defaults.
That router has VPN capability and perhaps a free VPN service from Netgear.
Check out the link at:
VPN access would be preferred to port forwarding.
Regardless of VPN and Port forwarding, you should be able to access the RigPi and Mumble when you are on the local LAN.
