If for example subnet1 is 192.168.1 subnet2 is 192.168.2 the wireless gateway is 192.168.3 Internet is something Then this is a pure routing problem. Then learn about routing via "route" However, with -stable (ie after 4.3) there have been changes made to the Aironet driver to do promiscuous on wireless and the submitter of the patch has bridged the wireless and wired network together. In that case you could. subnet1 is 192.168.1 subnet2 is 192.168.1 the wireless gateway is 192.168.1 (bridged to subnet x) Internet is the default route. Then use could use netgraph bridge to tie the wireless adapters to your wired network. It would appear to be one big network. Even without the patches some things using VPN tunnels and bridging could tie stuff together. Really in this case subnet1 & subnet2 are effectively the same network. I haven't personaly done this (except routing) but giving you and idea of what to persue. Doug A.
