some elements are missing, eg: either iptables-nat rules on B or routes
(maybe dynamic, eg RIP?) on A must exist, otherwise C won't be able to
even reach A. Let's assume no NAT on A.
C can't get past A: it's possible as A knows about 192.168.2.0/24 but
nothing about 192.168.3.0/24 and thus does not let it go through (and
even if it does, it doesn't masquerade those packets).
1) make shorewall aware of the existence of C's network by adding nat
rules on A to allow C "reach the internet": iptables -t nat -A
POSTROUTING -s 192.168.3.0/24 -j MASQUERADE
2) bridge the two NICs on B in a bridge and suppress B's DHCP server
(thru fedora's network configuration system)
I would go for #2 unless you specifically need to separate airwaves from
no pints for me as I failed again to get a dream job in my dream city :|
