Internet cafe setup

Ok lest start with what i am doing and then i will get to the equipment. Ok I am trying to run internet for my platoon in iraq. I am going threw the company oifnet.org. i am trying to run about 25 people. My modem is a DW4020. I already have the newest version just waiting on commissioning. I currently have 14 people. I have a dlink DI604 router, which i am currently not using due to ip add issues working on firmware. My current one is a Linksys WRT54G router. I have 4 switches just to save cable 2 dlink 1 linksys and 1 other.
I get 5 GB per month with a daily limit of 200MB. The GB's are only measured from 10am to 10pm my time (bahgdad). Once i go over and i become untrusted The attachments show the scales. The daily limit is 200MB and as long as i dont go over 200 it leaks them out at 75 Kbs. My biggest question is what do you recommend to run this. I also have a programmable cisco switch in the mail should be here any day.

Ps Monthly service is office 1000

 

I think what you are doing is great, but I see many issues with it.

First the bandwidth allowed...

200mb daily limit for 25 users? Not good at all. You will need to have a filtering solution in place to keep users from abusing the link. If people start streaming music that 200mb is going to get chewed up quick. Also, all thoughs image heavy myspace pages...

You can rate limit each port on the cisco, thats a start. Also, I would not make wireless available to everyone. Better to have them come to you and connect to your switch when they want to browse.
