ive set up also a new 1.2b1 box with 3 epro100 nic´s
regardless what i set for rules
(even any to any)
nothing seems to work.

networks 

lan : 192.168.123.0/24
wan : 192.168.124.0/24
opt1 : 192.168.10.0/24  dhcp & captive

could get only some data if i bridge opt1 to lan,
but then everything pass throug regardless of filter rules (yes bridge filtering enabled)

same happen if i use the 1.1 image for this box, 1.0 works fine but has no captive funktion
