It suspect the problem is with your router/firewall.

1. When you 'ssh -X homeserver -p 5317' the ssh is from within your own
intranet. That appears to be normal and working.

2. When you try the same via the public internet the connection is
blocked or mis-routed. From your other post:

It would be impossible to tell what the issue is on your router and/or
firewall unless you identify what the router/firewall is. If you'd like
to test from outside, drop me a note directly and I'll be happy to
attempt ssh connections to you from the outside. You'll be able to tell
who/what it's coming from that way. No need to give me any password etc,
just the details of the port & with those I'll be able to tell you if I
get an ssh prompt back from your system.
