So after all the thinking i have decided before buying anything to do the minimum security setup with the hardware i have just to make sure i will be able to make it work.
If everything will go smooth i will go ahead and get something better for more security.
Here its the hardware i have now, and i would like to get something of it:
What would be the best connection architecture with it in order to give out free internet for dynamic IP but stop users from simple access of office computers? (office computers are on static IPs)
Thank you very much.
