[pfSense Support] lan firewall

[dny]

hi all.

i need to setup firewall that bridge two LAN using wifi.
setup like this:
lan1 ----- firewall1 ----- wireless bridge ----- firewall2 ------ lan2
internet -----|

because the wireless is very prone to virus/worm spreading,
(many cases the wireless just 'die' caused by this)
i want to make sure (by using firewall) that only allowed
traffics (only web, rdp and windows file/print sharing) that may pass the wireless bridge.
and all other ports closed

can this implement using pfsense?
(note, firewall 2 dont have wan port)

how to setup network like this?
i'm linux/bsd newbies, so please give more detailed step-by-step guide for dummies...


tnx&rgds,
dny
