Oh, and yes (actually reading what you wrote), running it through a laptop can work. Laptop wifi connects to your mobile hotspot, ethernet connects your laptop to the WAN port on a router (or directly to a switch or desktop machine), give the ethernet interface a static IP on a different network from the mobile hotspot, e.g. 192.168.11.1/24, then run the command: iptables -t nat -I POSTROUTING -o wlan0 -j MASQUERADE (where wlan0 is your laptop's wireless interface connecting to the mobile hotspot). Then you'll need to run a DHCP server providing leases on the ethernet interface only, and you are done. You could do something similar with a router running OpenWrt in place of the laptop, with the radio in client mode, acting as the WAN interface. There, you have the nice advantage that the router already has a DHCP server built in. The key is to avoid trying to put a client-mode interface into a network bridge with anything. That is disaster, don't go there. Routing works fine, so use it and MASQUERADE'ing (i.e. NAT). -- Russell Senior, President [email protected] _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
