I have a strange problem that is happening w/ FreeBSD & pppd.  I am
connecting to my employer (which is also an ISP and which assigns
dynamic IP addresses) using pppd and FreeBSD 2.1.0-R.

I connect using:

pppd connect 'chat "" ATDT####### CONNECT "" user: <username> word: 
 <password>' /dev/modem 38400 noipdefault crtscts modem defaultroute

I get connected and everything works fine EXCEPT if I try to connect to
another FreeBSD machine on our network.

I've tried connecting to three FreeBSD machines -- if I telnet to those
machines, it connects and hangs.  If I telnet to those machines on port
80, it hangs.  I can't ftp or rlogin to those machines, either.  Ping/
traceroute show no weirdness that I can determine.

If I telnet to ports on those machines which are running custom written
servers that I've (or others) have written including a MUD and a chat
server, it seems approx. 800 bytes or so of data is sent and then the
connection freezes.

HOWEVER, I can telnet/etc. to any other machine that I've tried.  AND,
I can make successful connections to ftp.freebsd.org/freefall.freebsd.org,
etc.

Any hints/suggestions?  I'm not a strong networking guy so the answer may
be very obvious to those who know much more than myself.  FWIW, I've used
pppd before w/ other UNIX OS's in a similar paradigm w/o a problem, this is
why I'm so boggled!

Thank you very much,
Rich.
