it definitely does not use IPX.

Do you want the PDC to be able to pass through the firewall? If so, why? 

But if yuou do you'll need at least 137 138 and 139 possibly more but
thats all the ones I know of.

Again why are you doing this: Most of PDC uses are LAN-centric and
generally shouldn't be passed through firewalls.
