RE: wireless interface sharing same subnet as wired
Ok, let me start over.
What I want to be able to do is share a single IP subnet between two private
Client 1: ethernet cable. 192.168.1.50 / mask 255.255.255.0
Cleint 2: wireless 192.168.1.60 / mask 255.255.255.0
With a 3-interface OpenBSD firewall in between the two. The fireall would
bridge the ethernet and wireless so that both clients could connect directly
to each other (ping or otherwise). And both clients would NAT out the same
common public interface.
The wireless network would use enhanced WEP + mac filtering for security.
Not perfect, but suitable for the intended application.

I think you will need to run DHCP for your wireless (or some other
'infrastructure'daemons) on your PRIVnet, filter these ports from the PUBnet
- but then just treat the wi0 as part of your internal network for NAT -
when you say bridge you don't mean 'transparent bridge' right? I don't think
that works with NAT. um no.

Subject: wireless interface sharing same subnet as wired
Is there a way with OpenBSD 3.2 to "bridge" the wireless and wired
I have a 3-leg firewall:
wi0 - private wireless
fxp0 - public interface
fxp1 - private interface
I have seen Linux and WinXP firewalls that allow you to bridge the private
and wireless interface to allow a single IP subnet.
Also need to NAT on the public interface for both private interfaces.
Any suggestions on how to configure this with OpenBSD 3.2?
