ORPort unreachable, though wide open



Hi list,

I've been setting up a TOR instance on a private gateway, with
the intention of providing an entry point for all users on the
local LAN. As a bit more traffic doesn't hurt me, I intend to
open up the server, though not as an exit node.

The setup is already working well, but there's one thing causing
me headaches:

Strangely, I keep getting messages that the ORPort is not
reachable. However, I can telnet to the public IP of my gateway
(static address) to port 9001 from either
- hosts from my internal network
- from the gateway machine itself
- from the internet

Thus I would exclude a firewall issue. There is no redirection
involved, TOR sits on the border of my network and the gateway
is readily available for a couple of other external services.

I checked everything twice and can see absolutely not reason why
TOR should have problems with reaching itself. What's exactly
happening when the reachability of the server is checked?

I would be grateful if anybody could enlighten me about what I
might do wrong here (or if this is a known bug).

All the best,
/Markus
