We have 2 ISP, one DSL and one Cable. We have added a wireless access
point to use for guest and members of the board. Is there any way to
have those users connecting via the wireless receive special IP
addresses that have a router gateway setting that points to the cable
modem router, which bypassess an internet filtering device.

Currently we have a single subnet. 192.168.1.0-254 which automatic
addressess assigned from 51 and up. DSL router is 192.168.1.2 and cable
router is 192.168.1.3.

Thanks.
