PIX 501 and Wireless Router

[bassmaker]

I have a new wireless router that includes switch ports for wired users. I want to put a PIX 501 firewall between the router and the wired users so that wireless users will not have access to wired computers. Things are set up like this: Cable modem is connected to wireless router WAN port. Wireless router LAN port is connected to PIX WAN port. PIX LAN ports are connected to wired computers. I disabled NAT on the PIX and put a static route in the wireless router to tell it to use the PIX WAN interface as the gateway to the wired computers.

The result is that I can browse to the wireless router from my wired computer and pull up the configuration web pages, but I can't browse to Internet sites. Any clues? Thanks.

chances are that the wireless router will not NAT your traffic behind the PIX. configure the PIX to NAT your wired traffic to 172.20.0.2 and try again.

I put in a default route and it still didn't work. I reviewed the facts and could not figure out where I went wrong, so decided to swap out the wireless router and put in a wired router. Then everything worked fine. Concluding that the wireless router was not working right, I tried to access the configuration and it died. Got a replacement on order.
