right, ill get down to business. We got a new cable modem/router today, and i have most of the computers in the house connected. My mac usually feeds internet to my desktop, so i can game my heart out on winXP :3 Well, new modem, and now it is not receiving any packets except the DHCP packs. IP address is correct between the two computers, just internet sharing is bonk.
OS X 10.5 (Rolled back specifically FOR this setup..) Windows XP SP 2 on a custom rig. Nforce4 Ethernet controller, Asus a8n-SLI motherboard.
Of course, trusty AlBook G4 fw800.
Help much appreciated! (No, seriously!)
