You may have to build an intermediate network between the two. DISCLAIMER: I'm just stating what I would try; there may be easier ways with your specific hardware like being able to turn off the router portion of the modem, etc. This is just one way I'd attempt it.

Looking at this from a left-to-right, outside-to-in configuration, I'd build an intermedaiate network like so:

Port:-----IP Address-----Def Gateway
Modem
Ouside:---PER ISP doc's
Inside:---192.168.0.1----(outside gateway)

Wireless
Outside:---192,168.0.2---192.168.0.1
Inside:----192.168.1.1---192.168.0.1

PC:
Outside:---192.168.1.2---192.168.1.1

Assuming all subnets are Class C (255.255.255.0) and "Outside" signifies the port furthest away from the PC.

At least that's the direction I'd go. Then let the DSL modem do the firewall stuff. If it has no options for that, let the wireless do the firewall. I'd suggest not doing both.

That any help?
