I have a wireless card installed on Fedora 4 system. I have the wireless connection open, DHCP enabled and have disabled forwarding for the "open" network. I use Poptop and Radius to authenticate and assign IP addresses on the tunnel and then allow forwarding for the tunnel address range. I now want to have all http requests from the "open" network to be directed to a opening/login page on the wireless server. Can this be done with iptables (conntrack?)? Would anyone suggest links or keywords for finding more information? Thank you. Kirk
