Easiest and quickest is to install the firewall - if it is not already in
your kernel, simply load it as a dynamic module. In a pinch (and if the
person causing problem is doing this by accident) you can try something
like "route add 22.214.171.124/32 127.0.0.1" which will make the tcp
handshake break. Which may cause the other end to realize somethign is
amiss. But it does not really stop the traffic.
