[LARTC] Allowing certain IP to browse

[andrew.goodluck at intafrica.com]

Hi all,
Need your input of the following:
I have a linux box(firewall)
-I want to restric some users not to browse but send emails only
Example: 192.168.x.2 up to 192.168.X.45 to send emails and browse, while
the rest(192.168.X.46 to 192.168.X.254) to send emails only. How do I do
that?
 thanx
Andy
