Hi,
I've been trying to figure out an efficient way of blocking unwanted traffic
which uses port 80 (or 443). In an ideal world, LAN users should simply
"behave" and use network resources with care. However, in a big network it's
likely that there be some uncivilized users once in a while.
I would like to block services such as LogMeIn (I suppose it works like
httptunnel from www.nocrew.org).
Until now, I have blocked specific IP addresses (such as the LogMeIn servers).
Has anyone used a more efficient/global solution (apart from blocking HTTP
access altogether)?
Has anyone already used l7 to do this (or can it)?
I know shorewall doesn't support l7 but are there any alternatives to detect
"non-HTTP" traffic going through port 80?
Regards,
Vieri
