We are setting up a GXW4104 and a HT814 at two different locations. Peer to peer no SIP server.
Each location has a static IP public address on a modem/router, and the Grandstream boxes will be behind the router using NAT with a statically set internal IP address.
I have tested the two units on a local network and all is fine, so now need to move them to there final separate locations where they will communicate over the public internet. No VPN.
Assuming any firewalls are completely open, what else would I need to do?
So set each of the SIP server IP’s to the public IP of the opposite location.
Any port forwarding? Or will it just know where to set the packets?
