I hope there is somebody knowledgable about networking...

I use a reverse DUN (Dial up cia BT to my PC). On the PC I have a webserver and I want to access the websites on that with the Treo 650. Which IP address should I use? Can I access IP addresses via Blazer?

My PCs IP is: (internal)
The IP/DNS is obtained via DHCP by my router

The IP of my BT network access driver is
The DNS is (my router)

Accessing the web works like a charm, using any of the mentioned IPs does not (searching...searching...). Does anybody know a way around this problem? (i.e. manually changing the routing table on the PC? How do you do that?).

Thanks for your help!
