Hello everyone,

I am currently using Pegolin as a standard reverse proxy behind a VPN provider that allows limited port forwarding (specifically, port 17787 for me). The Pegolin admin interface is successfully accessible externally at pegolin.mydomain.xyz:17787. However, any resources or applications hosted behind Pegolin are not accessible externally, auth seems to fail since pangolin is passing 443 based redirects back in the auth URLS.

I have included a schematic of my intended use case.

Port 17787 is forwarded from the VPN provider to my internal network.
The Pegolin administrative dashboard is reachable via pegolin.mydomain.xyz:17787.
Services proxied through Pegolin (e.g., web applications) do not become accessible externally through the same forwarded port.
I understand that this is an unconventional setup, as most reverse proxies operate over standard ports (80/443), but the ability to forward services through a single custom port would allow Pegolin to be accessed when port 443 and 80 can't be exposed.
