I have a simple home network that uses a router with a firewall and a wireless access point, like so:
Internet (DSL/POTS line)
Right now my wife's and son's wireless devices access the internet via the router's wireless on the 10.0.0.0 network. I'd like to move them inside the firewall to 192.168.1.0, and turn off the router's wireless access point. Can I do this by putting a PCI wireless adapter on the firewall and giving them 192.168.1.0 or would I have to create a third network and a set of rules to get them into 192? Lastly, I'll take any recommendations for such wireless cards.
