No, not usually.  If you want to stop HTTP tunnels, you need to
use a web proxy, like Squid (perhaps as a transparent proxy),
with some kind of filter.  I don't know of any existing package that
does this, or even if it's a workable solution.  Are you concerned about
specific HTTP tunnels, like AOL?  If so, you should be able to defeat
that by black-listing the IP addresses.

A hardware firewall?  Oh, this question again.  It really depends
on your setup, but having a separate firewall is almost always
recommended.  You might look at www.floppyfw.com.

You might also look for 'NetFilter', which is the name
for the kernel-portion of the new Linux firewalling code.
http://netfilter.samba.org is one of the mirrors for the project's
home page.  There are docs there and mailing lists.
