Manually specifying endpoint IP address?

My ISP unfortunately has been behind a double nat and I cannot pinhole the port required. Currently my connections max out at 2MB/s which is OK for most things.

I have a VPS that I use to tunnel certain traffic inside my LAN. I would like to pinhole the proper port here, however my TS Node shows my ISPs external WAN address which I cannot use. Is there a way to override and set the endpoint IP address?

You could open a port on the VPS. As long as one end can establish a direct connection, then you won’t be relayed.
