Procedure

1. First, you must set up a network connection between the local and remote networks using a VPN tunnel technology such as SSL, PPTP, L2TP/IPSec, OpenVPN, IKEv2, SSTP, etc.
2. Once a VPN tunnel route has been established then you may need to “allow” these ports in the hardware or software firewall:

3. In addition to these firewall ports, the PC must be able to exchange ICMP (ping) echo messages with the Q-SYS core processor.

A remote VPN connection functions properly because the remote user has access to the local IP address range used on the destination network. In this case, packets never have their Layer 3 IP headers modified from end-to-end. In other words, these local IP packets are “tunneled” to the remote machine.
