Zxwall P1 Rules

So i got my ZyWall P1 firewall. Got all my rules set up, ports forwarded, logs set the way i want etc etc. When i put it between my sbs03 and fios connection i get NO incoming activity. I know all the ports are forwarded and the rules are right, but i may have them in a bad order or something. Also, i can allow all traffic by setting the default rule from wan->lan to allow, but then why have a firewall… so, anyone familiar enough to point me in the right direction?
