Can you describe the slowness? I have an identical problem going
(freebsd/netbsd) -> slip/ppp to (linux/netbsd gateway) -> netbsd1.0
but no problems going
(linux) -> slip/ppp to (linux/netbsd gate) -> netbsd1.0
(*bsd) -> slip/ppp to (cisco) -> netbsd1.0
The problem only seems to exist when slip/ppp and two BSD machines with
a non-cisco gateway/router are involved.
My symptoms are horrendoulsy slow tcp connections where
I telnet to the netbsd machine and wait maybe 1 minute for the login
prompt, then maybe another minute for the password prompt and so forth.
Some people suggested MTU or modem compression problems, but that
doesn't explain why it works with linux. Others suggested options
to telnet, but I've a suspicion that this is a much lower-level problem.
