The inputing rules have been enhanced so one can redirect form traffic
and send it to some hosts. It is using the ip_masq_mfw kernel module.
A new field was added to the form. Before, one could only intercept
traffic and redirect it to some local service on the firewall. Now, the
extra field allows you to redirect to another machine.
This should simplify the old "redir" setup since you do everything from
the same dialog. It allows arbitrary traffic redirection, not just
TCP. Check it out. Not tested much though.
