Adding Virtual Interface on LAN

[nicholas]

Hello good people,
Is it possible to add a virtual Interface on captive portal.
A little background of my setup
  I need to activate captive portal to filter wireless network and as per the above setup pf-sense cannot ping wireless network. I need a virtual interface that will bridge BTN the router (Pfsense) and the wireless network for captive portal to be effective.
Any other suggestions on how i can effectively archive this will be highly appreciated.

NB: am a bit of newbie on pfsense/network so try to go easy on me  ;)
Thanks

0/ Is the switch managed/VLAN capable? If not, go to shop.
1/ Huh? Bridging and isolation in one sentence?
2/ Where's the wireless magic thing? Cannot see any.
3/ Turn OFF the firewall on whatever you are pinging.
4/ Look at the firewall logs
5/ If you still have problems, you need to post your interfaces setup, firewall rules etc.
