Limit outbound SOCKS proxy requests with pf (self.openbsd)

Hi everyone,

For a very special use case of mine, I need to allow users to connect over SSH to my server to setup a SOCKS proxy:

ssh -D localhost:1080 -N my.server.domain.tld

However, I only want them to be able to reach 127.0.0.1 through this proxy (so, my server itself).

Is that even possible ?

Yeah that's me, though that was a very long time ago haha. That's an awesome story, I could never guess simple posts like mines could be that much inspirational ^^ Thanks for sharing !
