Hello everyone,

   My boss asked me to do a gateway server, which can control the access
   to internet users on our LAN.

   I have a DSL Router connected to internet, -> should be connected to
   FreeBSD 4.8-R box, and this box provide the internet access to the LAN
   and control it.

   putting the box to internet, no big deal, My question is
   How to controll the Internet access to users on lan?
   For example:
   To give this certain IP an Internet access and to Block the other IP
   from having the internet access (with keeping the LAN up for the IP) ?
   Also to set something like, Give this IP on LAN an internet from this 
   hour to this hour?

   Can someone please give me an Example on ipfw?
   and is the ipfw the only way to do it? 
   I never used ipfw, so a kind detail help is really appreciate it.

   sorry for long email, and thank you.
