[Plug-security] ipchains vs iptable

[Carl Parrish]

Rusty are you saying that I should change my chain to something like
this:

ipchains -A input -v  -i $EXTERNAL_INTERFACE -s any/0 -p tcp \
  -d 8081 -j REDIRECT $WEB_SERVER:80

I'm still not sure I understand REDIRECT correctly is there a diff
between REDIRECT and redir????

Thanks, 
Carl P.
