I have Comcast internet with a NetGear CM 1200 cable modem. This connects into Google Mesh wifi router.
I am trying to connect a ClearNode AllStar node which needs ports 5198 and 5199 forwarded in both directions.
I have forwarded external ports 5198 and 5199 to confirm internal port 5198 & 5199 UDP and set the node to a reserved IP address (static) but I continue to fail the firewall test.
Sorry about the late reply here and for the issues you're seeing with your port forwarding efforts. I imagine that's quite frustrating. We have a help article for port forwarding, which you can see here: https://bit.ly/2VFhZ5S.
If you're setting everything up as mentioned in the article and you're still seeing issues, please let me know and we can look at more specific causes.
