Sure it is.

First, on machine B, you need to enable IP packet forwarding in the
kernel, since it's off by default. You can do this on the fly with:

ndd -set /dev/ip ip_forwarding 1

This will let you pass packets between interfaces on this
machine. Remember that this value doesnt stay between reboots. Just stick
it at the end of /etc/rc2.d/S69inet if you want it to.

Then on machines A and C, you must set the apropriate routes on them so
that they can talk to each other through the "router", which is machine
B. Consult the O'Reilly TCP/IP boo by Craig Hunt if you're not sure about
this.
