Splitting your wifi networks

[armitage]

HI there.
Im going to be getting a wifi connection again to my local wisp and i was wondering that if i connect to a community wifi group how do i stop them from using my internet connection? I've got 2 pc's in my place that i want to have internet enabled but the other normal pc's on the network i don't even want to let them know i have net access.


Does anyone know of a good proxy prog maybe that can handle just the access part? I need something that's kinda painless to install an use pls.

602 lan suite pro. they have a free version if you have less than 5 users.

not sure it will do what you want it to, but it is a all-in-one app for email/web/internet access. it is quite feature packed and easy to use/configure.

btw, you can uninstall it afterward without it messing up ur system (unlike some other similar packages).

I'd go with one of the access points that run linux for the wifi connection, and just filter who was nat rights using iptables.
the other option is to connect a gateway/firewall pc directly to the access point they give you, and have a 2nd nic on that firewall that goes out to your switch for the network, something like (smoothwall + FFW mod) or pfsense/monowall could do the job, allowing you to filter who can and who can't access net via web console.

I'd try minimize the hops, specially with wisps sharing ip's, generally, with a wisp setup, you should get at least 3 hops before you can access net, ie doublenatting at wisp, 1 more hop to u, adding another firewall, will lengthen this chain, you should try keep it as small as possible.

hmm, dorris, do you think this is possible with a Gigabyte B49G. Caus I have had the exact same concerns in my case.

hyperthetical question relating to this ...

Can you connect many devices/appliances to a single card? As an example, I buy 1x 802.11g card for my PC. From this PC I link to another, my WISP for internet, my wifi PDA, my Nikon wifi camera and stream to my hi-fi/tv via wifi. Possible?

@dolby!

Depends on the wifi card, but if they are all 802.11 b/g compatitble it should work with everything in your house, for example you can even have an wifi a/p to share a networked printer and so forth.

The only problem with the wisp. Firsly it depends how their setup works and secondaly it depends on the strenght of you arial on the pci carb, usually they are only 8 and thats not enough.

My wireless ADSL router lets u choose the MAC addresses that are allowed internet access. A MAC address is a unique number given to ur lan card. Donno if this helps... Maybe a similar one for ur WISP... i got a linksys WAG354G
