You're not seeing everything. First, "iptables -L -v" will show you more information. Second, there are other tables. Use "iptables -L -t nat" and "iptables -L -t mangle" for instance.
After a fresh boot, Machine B can't see the outside but can see A. Also, A can see B. Then a restart of the firewall causes B to be able to see the outside world.
You need to reconfigure the firewall service so that it runs after the network service. It's probably trying to learn what networks are attached to each interface, but can't because the interfaces aren't configured when it runs.
