Here are the port forwarding rules that worked for me:
=================
I have a Verizon G3100 router. Set up these port forwarding rules, but no luck:
Application: Roon
Original Port: 55000
Protocol: TCP
Fwd to Addr: 192.168.1.8 (my ROCK static IP address)
Fwd to Port: 55000
Schedule: Always
My info (I wiped out a couple of the octets on my external IP address)
{
“connectivity”: {“status”:“NetworkError”,“status_code”:504,“error”:“error: Error: ETIMEDOUT, response code: undefined, body: undefined connected? undefined”},
“external_ip”: {“actual_external_ip”:“96.245..”,“router_external_ip”:null},
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“server_ip”:“192.168.1.1”,“found_upnp”:true,“error”:“doaction request return statuscode: UnknownError”}
}
