This weekend, I thought I'd give a shot to firewalling my home net better
than it is.
========, ,========================, ,==========
Switch ------ Zyxcel Router/Modem/FW ------ INTERNET
========` '========================' '==========
For arguments sake, lets say the internal network is 192.168.1.0 and the
firewall/router/modem carries one non-routable IP (192.168.1.1) that acts as
the gateway for the internal net, and one routable IP that is the Internet
What I would LIKE to do is (ditch the router/modem thing.. it does not do
ANYTHING next to what I want.;) )go SWITCH to OBSD FIREWALL/NAT to Zyxcel to
INTERNET. I would set the Zyxcel to forward everything (any any) to and
from the OBSD box.
A) Will this work? (I understand routing a to b but not the protocol layers)
B) Is there someone who would be willing to help me go over my rulset to see
if it is correct?
I have made exactly one attempt, and it failed.. then it occured to me that
maybe this just WON'T work at all.
If this WON'T work, what type of device should I buy for my OBSD box to make
the PPPoE connection to my ISP? (I would actually like to know this anyway)
