I hate to ask stupid questions, but can you make sure that your shell machine 
and firewall agree on the IP address for maple.he.net?

I just checked this.  I telnetted there and my identd got no probes (I 
actually stopped my inetd, so the machine got no probes at all).

What "connection refused" usually means is that the machine is up and 
reachable, but there is no service on the port that you're trying to connect 
to.  That's why I'm wondering whether your two machines are connecting to 
different servers.  However, through the magic of ipchains, I believe that 
it's possible for he.net to have things set up to do checks like probe your 
identd and then fake a "connection refused".  But it doesn't look like that's 
happening here.
