Alright, here's my setup. Windows XP Pro (Desktop) dials a dial-up connection. It is shared through it's Ethernet port. I want to connect this Ethernet port to a WiFi router to share Internet and LAN. I have a WRT54GS and a WRT55AG. My general issue right now is that I want the desktop and the router on the same subnet, so it's more of an access point than a router. I could simply not use the WAN port and connect to a switch port on the router... BUT, the hold up here is that I want to use the DHCP in the router, which will assign the router's IP as the default gateway. I need the XP machine to be set to the default gateway (192.168.0.1). So, I understand there's no open source firmware for the WRT55AG. But, for the WRT54GS, is there open source firmware that would allow me full control over the DHCP scope? Or to set up this router as an AP? I don't really have a problem with using gateway mode, but the issue I always have is that if I put my WiFi router on the subnet of say, 192.168.1.0, and my desktop is 192.168.0.1, I can't seem to address UNC paths to the desktop... like \\DESKTOP-PC. I can do \\192.168.0.1 . Also, I'd like UPnP to work. Any ideas?
