Question : Multiple IP Range - separate wireless from network

I've got an ISA firewall that is on a network range of 10.2.16.xx - 10.2.19.xx.  I also have several access points that I'd like to have give out 192.168 addresses through the built in WAP DHCP server.  How can ISA be configured, hardware-wise and otherwise to support this and keep them on completely separate ranges?

Answer : Multiple IP Range - separate wireless from network

Add another NIC with 192.168 IP address and connect it to APs. Define another Internal Network in ISA and set proper routing rules in ISA. (Internal2 --> Internal "router")
or
Just add another IP to your internal NIC (beside 10.2.)
