That's my question really. I'll plug into a network (not ADSL), and want to route from the other PCs.
Basically it's for our Motor Show stand. I can plug a PC into the exhibition centre's network (1 cost), but would rather then have my own wireless net rather than have to buy another 2 connections.

That could do exactly what you want. The only problem is if they are a bit cute and set it up to intentionally stop something like that working. It's got NAT etc so you would only need the one IP address.

Or has it being discussed at length and I didn't notice?

Can you not just plug a wireless access point into the network, and access through that?
That sounds like a better solution. Is that feasible then?
I've got a Linksys jobbie here. Could I use that?
It'll need NAT like the Netgear jobbie ^ (so you only need to grab one IP address) which I doubt a straight AP will provide. What's the model of the Linksys?
BliarOut said:Network doughnut here. What cuteness could they employ? If I've got the right end of the stick, home-user type routers by default use NAT so that the outside world only sees a single IP address. The router replaces internal IP addresses with its own on out-bound packets and, by remebering who requested what, reverses this process on in-bound packets. Is that right? If so, how could ExCel detect that NATing was taking place?

MAC address checks, not difficult if they really want to, but I'll bet they don't.
edant mode: The MAC Address of any clients 'disappears' once you cross the router... only the Client IP Addresses might be visible in certain protocols, but again all out bound traffic assumes the IP Address of the Router.
The checks are actually made using heuristics of the number of TCP/IP sessions that are opened and sometimes UDP is monitored too - usually DNS.
Generally by monitoring these parameters you can deduce how many clients are behind the router, but as you said, they've probably got better things to be doing.

You'd be suprised.
Having facilitated events at ExCel, internet access is one thing that they are pretty hot on (It's a licence to print money at the end of the day)
We used a single connection for one of our events, and then used a router to give us enough internet connections (Wired solution rather than wireless)
Worked a treat.

Ted,
This is what I do at the NEC with my firms stand - they supply a CAT5 cable (literally) and a dynamic IP, which you can then do what you like with.
Most Wireless routers can handle it, but you'd be better off with a firewalled router - just in case. Obviously then you can hang whatever you like off it as the router will be dishing out IP addresses DHCP stylee...
HTH

Edited to add they will have a subnet that you can't use, but I'm sure unless your name is Ford they won't be getting Kung Fuey on your ass if you hang a couple of machines off the connection. If you do use wireless though, make sure you you use the best encryption method, because you WILL have some t
t trying to break it - its a public show and geeks will try anything and everything to see what they can get too... >> Edited by neil_cardiff on Thursday 18th May 08:58

Not sure how monitoring UDP is going to help you (if it's just DNS as you say, then why not install a DNS caching server on the machine that is supposed to be accessing the Internet)
TCP sessions? In that case just tunnel out of the place to a known point on the Internet.
1 TCP connection for as many sessions as you like.

To be honest chaps, if they are monitoring traffic, they will leave most clients alone - they'll have a HUUUUGEEE connection (probably a 100Mb) and they really won't give a toss if someone is adding a couple of extra clients on.
What they do get funny about is when servers appear and they get most unhappy then
neil_cardiff said:Point about the Linksys WAP was that if it's a straight AP then it won't do NAT and they're probably not going to give IP's away for free when it's a revenue stream. Any NAT type solution will probably work but I wouldn't necessarily want to rely on an MS ICS if time or reliability was important.
