Re: (ASCEND) more stuff!
I reported this problem a while back to Ascend but it happened to be in a
router doing NAT and I *assumed* (never assume so says Felix Unger :-) )
it was a NAT problem. I never tried it in a non NAT configuration until I
read this posting. This is a bogus bug and should be fixed.
The terminal mode of the routers is used mostly for debugging things. I
noticed this problem when using NAT because connections to SMTP servers
were painfully slow. This was because many smtp servers connect back to
the identd port of the machine making the connection (in the case of NAT,
the router itself). I needed to add a NAT static map of port 113 to the
router so it refuses the connection and lets smtp get on with its life. I
had to go to a workstation to test it -- I couldn't connect to smtp from
the terminal mode.
