Greetings,
I'm setting up a system using FreeBSD and a 56K frame relay line to the rest
of the world. This is a small IPP where most of the traffic will be between
the FreeBSD box and the Internet, but there will eventually be other local
machines as terminals. I'd like to minimize cost and retain the flexibility
that we all know and love (I've been using FreeBSD in two different modem
based installations for almost a year). Here are what I consider the options
given my admittedly limited understanding of the situation:
Option A:
----------- serial port ----------- 10bT
>---| CSU/DSU |--------------------| FreeBSD |--------->
----------- frame relay ----------- IP
$200
Option B:
-------------------- serial port ----------- 10bT
>---| CSU/DSU | FRAD |--------------| FreeBSD |------->
-------------------- PPP ----------- IP
$1000
Option C:
-------------------- 10bT ----------- 10bT
>---| CSU/DSU | FRAD |---------| FreeBSD |------->
-------------------- IP ----------- IP
$1300
Option D:
---------------------- 10bT -----------
>---| CSU/DSU | Router |------+--| FreeBSD |
---------------------- IP | -----------
$2000 |
\------------>
Option A would be preferred, but will it work? Can FreeBSD talk to the
CSU/DSU directly? If not, option B is reasonable, but option C is only
a little more expensive and avoids having to deal with a serial port on
the FreeBSD machine (although two ethernet cards are needed). Option D
is for only if nothing else works.
