There's no need for a default route in these cases since the traffic is
all going to networks connected to the interfaces.  If he was trying to
send packets outside of these direct connected networks then he would
need a default route, I agree.

As to the firewall, he's set all of everything to ACCEPT in all cases at
this point so traffic "should just flow" (I hate saying "should just"
'cause whenever I say it, it doesn't)..(might as well just turn off the
firewall software actually during this testing...that would take one
piece of the puzzle completely out of play).
