https://bbs.archlinux.org – I followed the wonderful guide at https://wiki.archlinux.org/index.php/Internet_Share and I can now share the wireless internet from my Arch box to my Windows box. I have the exact setup as the guide so the card forwarding packets on the Arch box has IP 192.168.0.1 and the windows card has IP 192.168.0.2. I can access the internet on the Windows machine and I can ping the Arch box at 192.168.0.1. (HowTos)
