Setup Acceptable Use Policy for Internet

My way is old school, but I simply do not allow connections until they read and signoff on a AUP. We do not use wireless and there are ethernet jacks setup for access, but they are not active until I change the configuration. But I do not have many vendors or visitors in my corp. You may have several. What method do they connect to the network you have setup and what type of network hardware are you using?

We currently have three corporations on the same floor, I am the IT company in charge of maintaining the networks for all three. It is pretty much not feesible to have contractors/vendors sign it everytime they come in and need to use the internet. We are haveing probably 10-15 different vendors/individuals that need access to the internet per week. We are currently having to make ip configurations to every vendor that needs access to the internet. The hardware that I'm using is a Sonicwall TZ 190 Wireless.

Your looking for what is termed a "captive portal" There are many out there, but cost money, and depending on your AP you might be able to buy one or use an opensource one. Or... you could use MAC address filtering (802.1x) and force folks that want to use the WIFI to submit a ticket, or something like that, to give you their mac address, and you could allow them to the AP manually... but that's not easy to keep up with.
We use our wifi DHCP settings to hand out a proxy server address (squid) and it looks at urls against a blacklist and some content rules to help enforce our AUP. Which is basically taken directly from:

That's a long call... you'd think they'd know their product better... There are better/easier setups for captive portals available, just takes a bit of searching, glad you found something though.
