1 wan + (3 lan on same network???)

[tiam]

hi,
i'm using pfsense on a pc with 4 interfaces. one is wan and the other three are lan. i want to  configure  3 lan interfaces in the same network(for example 192.168.1.x, 192.168.1.y,192.168.1.z). how i can do? i viewed that i can bridged them together but what's about the firewall's rules , when i choose to block a service on one interface , i'll block it also in the others two or not? and what'about the gateway's of this three.  ???
thank's for help.
i hope to had not post a just answered question. ???

Could you elaborate on what your goal is?

The questions you ask are for a setup which doesnt make much sense.

Firewallrules are applied on the interface on which traffic comes in.
Regardless of the subnet attached.
If you bridge two interfaces together:

• you have a rule on one to block anything
• and a rule on the other to allow anything
  –> you can connect to everything from the "allowed" side
  --> but are block to everything from the "disallowed" side.

uhm..i think i'm wrong. i applied all rules on all internal interfaces, not on the wan one.
effectly there 's no sense in what i did.
