I use a redhat linux box to manage my LAN which has 30 windows XP systems. The linux box has a firewall installed/configured "GUARDDOG". Presently i am having 2 problems that i really need to solve.
1. I do not want to make my IP shown to the public. This is a security risk cos i use the 30 windows XP systems to run a public internet cafe. I suppose squid should be able to do this for me and I have squid installed but not yet fully configured. Any suggestion on how to get it properly configured will be appreciated.
2. The main issue that i will like to solve is setting a bandwidth limit (upload/download) for users and also how to get some sites restricted. I have read quite a number of post on the site and found a bit of information on using squid to limit bandwidth. I wiould like to know how to configure this as i am new to squid entirely (an intermediate expert in linux).
Any other advice on how to limit bandwidth usage apart from squid is gladly welcome.
A quick reply will be greatly appreciated.
