Hello, I wonder is there a way to connect two phisical networks on ethernel level in a situation like this:
I have two subnets(subnet1,2) connected through 2 aironet PCI4800 NICs(Cisco Aironet 340 Series) working on gateway1 and 2.(FreeBSD 3.3 and 4.3 machines)
-------------------\                                 /-------------------------    
                    |                                | 
   gateway1----->---------------<---------------- gateway2    <-------------> Internet
                    |                                |
-------------------/                                 \-------------------------
subnet1                                                subnet2

I was told I could try using ProxyARP, but if I do so, I'll manege to make machines on subnet1(for example) to see subnet2's machines. What I need actually is some kind of bridging, and I don't know: 
1) can I  use bridging(turning on promiscuous mode) on aironet
2) on gateway2 i have ipfw
As a third suggestion I got the idea of using netgraph.
Allright, I'll appreciate any ideas for what way do you think I should go ahead.
Thanks in advance
