I think I'll give the laptop idea a try. It sounds much easier (for me, anyway). If I actually need it, it will be later next week. I've got the tablet, router, and two laptops with me, and not in use, so I can test all this out before next week, once I get the time, all while still having this Comcast connection at our friend's place so I can maintain my connection to helpful resources, such as this wonderful group. -- Regards, Dick Steffens ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

How long do you need it for? Probably a few days to a couple of weeks. When I get to it, I'll give the laptop option a try.

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 russ...@personaltelco.net ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

It's not totally simple, though there may be off-the-shelf solutions too, but if you have an access point that is supported by OpenWrt/LEDE that also has a USB host port (many modern ones do), you can install kmod-usbnet and plug your USB dongle or USB tethered phone into the access point's USB port, and away you go, wifi and/or wired but with WAN provided over the USB connected device. PTP has built such things before. We had one at OSCON a few years ago, as a party-trick. Wifi is/was horrible in the exhibit hall, but it worked. -- Russell Senior, President russ...@personaltelco.net ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
