Topic: How can I block port 80

[David Trask]

Here's my situation.  I have 2 e-smith boxes....one running Stephen Noble's DansGuardian Module along with Squid and another running as my router/firewall/DHCP server.  What I want to do is block access to port 80 on my router box so that the kids here in school can't simply bypass the filter by changing or disabling the proxy settings in their browser.  How can I do this....can I do it for a range or a list and can I leave certain machines (like mine) out of that block?  Any ideas?  Thanks!

IN ...

/etc/e-smith/templates/etc/rc.d/init.d/masq

added a file ... 47DenyWWWConnects

which contains ...
{
 $OUT .= " /sbin/ipchains -I input -y -p tcp -s 0/0 --dport 80
 -j DENY\n";

}
