If you're thinking DHCP or BOOTP, à la Cisco "helper-address", then you would want to use a DHCP Relay Agent, which pfSense does support. Otherwise, I'm not aware of any way to do what you're describing. I can't even think of a way to do it in OpenBSD-current pf(4). TCP is fairly easy to NAT, but AFAIK all UDP NAT functions have to be hardcover. The other common case for what you describe is Bonjour/Rendezvous/zeroconf/mDNS. I don't think pfSense supports proxying that traffic... that's currently a bleeding-edge feature in some commercial WLAN controllers, and will cost you a noticeable amount of cash. The thing is, what you describe pretty much has to be handled by an application, not just firewall rules... actually, if it's mDNS you're concerned about, the Avahi package *might* do what you want, I'm not sure.
