Hi all,

I'm getting some strange delays on connections to my workstation on my
local network.  I can connect OK, but I invariably get delays of up to a
minute before a connection proceeds.  Once the connection is up and
running then the responsiveness is fine.

This occurs on all service protocols I'm running on my local network
(pop3, ftp, ssh).  I've looked in the logs, and I see no errors, retries,
or other likely culprits for the delays.  Ping times over the internal
network are nice and fast.  Connecting to localhost from the server
responds instantly.  There's no delay at all when I connect to the
workstation via ssh from the net.  Also, there's no delay if I set up a
"service" using 'nc -l -p whatever' and connect to that from inside my
network.

My workstation is doing NAT to the cable modem.  If I use a machine on my
local network to connect to a machine on the net (using any protocol) then
the connection is instantaneous.

Does anyone have any suggestions where I might find the source of these
delays?  If I were getting errors in my system logs or something then I'd
have something tangible to follow, but instead the only thing wrong is
that connections take forever to get through.

Any suggestions appreciated.

Regards,
Paul Gearon
