I have an OpenVPN Access Server.

I am attempting to use openvpn so that for when I hit those wifi networks that seem to only like TCP or only like 80 and 443, I can still receive calls.

The problem is, I've tried everything, I can find but the N810 just seems to refuse to connect to SIP via VPN.

I even tried SSH port forwarding, which my iPhone it works, still refuses. Even same exact sames and using socat, no luck.
