# CROSS POST - comp.unix.bsd.openbsd.mi,fa.openbsd.tech

Hi,

I have 3 computers, one with openbsd, one with linux and one with windows,
the obsd box has 3 nics, one to the internet, one connected to the lin box,
and one
too the win box.

What i want to do:

Setup the openbsd box in such a way so it acts as a software hub - so i can
have
the other two machines with 192.168.0.x addresses , and they can ping
eachother
through the openbsd box ( that has a 192.168.0.x  address too ), how can i
configure
the openbsd box to do this?

thank you in advance.

ps - the obsd box is 3.2, the nic's are we0  ( net ) , ex1 ( win ), and ne3
( lin ).

Wait a second, after doing a little research, i'm basicly creating 2
subnets, with the size
maximum host capibility of 2 on each subnet!

would this setup behave as if they were all connected to a hub with the
netmask 255.255.255.0 ?
( i wouldnt think so. )

Its important that all my hosts are all on the same net.

If not, how can i turn my openbsd box into a software hub, and have them all
on the same subnet ?
