Default mobile tethering a linux network

Mobile rates are becoming very competitive to landline rates. I can find out how to tether a laptop to a mobile by making the mobile a hotspot, My question: can this be done with more that one computer to a single (Android) mobile, even if this means purchasing some USB wifi sticks? If it is possible, please outline what has to be done. What are the security implications? Can I still run a http service through port-forwarding?

Hotspot is just another wireless network as far as the OS is concerned. Enable wifi. Connect to the wireless network corresponding your hotspot.

BTW, you can connect one machine to the phone without wireless using USB tethering.

Also consider a USB cellular modem as an alternative.

Thanks guys.

I don't have my new phone number yet -- it is coming later today.

I am looking at connecting my landline router (wirelessly) to the hotspot,

Note that some of what is technically feasible may be prohibited by contractual terms of service. That sometimes appears as restricting tethering to none, a single computing device or small number of mobile devices, not routing a LAN through it.

Typical devices like most phones can't have wifi in and out simultaneously (a normal hotspot is 4g in with wifi/usb/blueooth out), the same likely applies to typical routers. Some routers may not even let you do wifi in ethernet out. One way to get around some issues without wiring up the hotspot is to have another device like a raspberry pi that connects to the hotspot via wifi and passes the internet to the router via ethernet. That's a fair amount of hackery to avoid getting a 4G router but if you have all the other gear already why not.



The main issue I've had with my mobile provider is that they enable god-awful parental filters by default and require id to disable them, so if you're the sort that tries to restrict who has access to your personal information you either have to lump it or use Tor or a VPN. They're definitely selling your browsing information like any other ISP so if that fits under your definition of security then again Tor/VPN. The limited things I've tried all worked (Tor/ssh/sftp), non-standard ports worked on LAN but I didn't try non-standard ports on WAN. I'm not masochistic enough to get into the darker side of networking full stop, this link suggests you might have issues: https://android.stackexchange.com/qu...-hotspot-to-pc

The way I understood the idea, is to use a cell phone as a hotspot wifi to route cellular data to multiple wifi clients.
In my neck of the woods, there are no issues (technically or contractually) in doing that. Theoretically you can have up to 256 wifi clients tethered to your phone hotspot. In practice though there may or may not be congestion in very high numbers (dozens).
You can expect a much better bandwidth/speed from the cellular-data network than DSL, Which is what the landline is.
My 2 cents.
ETA your existing router world be unnecessary since the cellphone can act as a router. Most routers don't accept input from wifi unless they are repeaters.
ETA ii one thing to consider is that a cellular firewall might not be as effective as a router firewall.
I recall about 20 years ago we had a project which would connect a computer directly to a cellular data connection. It was under constant connection attempts from IP addresses that originated from China. It had a go to my pc account which was regularly logged in by unknown visits. Hopefully safety has improved since then.

I've taken Nick's advice and ordered a 4G router -- 4 LAN ports, up to 64 connections, dual band etc. If it works I'll ditch my landline with its pitiful transfer speeds.

Well, that little exercise cost me 200 bucks for a half-decent 4G router and early exit fees from my landline provider. The running cost is marginally cheaper for top speed and unlimited data, but the speeds -- oh boy -- are 20 times faster both up and down. Those Mersenne proof files will be uploaded in a couple of minutes!
