Yeah, I feel like we’re missing some info here.
I have to admit that I have no experience with yuno. Always seemed interesting, but not like something that fits into my work flow.
If they’re self-hosting at home (which I’m also doing for some services), I’d presume they’re probably running their stuff on a single machine, so I’m not sure where their router would come Into it. The data the cloudflare tunnel process receives should look the same to the router no matter the port it is ultimately sent to, and when it is sent to an address internal to the machine, shouldn’t pass through the router again.
Interesting. As I said, I never tried yunohost. I usually work with podman, and just assign local ports to pods, then route traffic to those ports internally, which seems to work fine.
Anyway, I feel like we won’t be solving OPs issue here. Still, interesting to see some of the problems people with different setups have to deal with.
