in this case--where you have ppp[0-9], you can also use the "+" notation =
to avoid having 10 rules that do the same thing; i.e.,=20

  iptables -t nat -A PREROUTING -i ppp+ -p tcp -m tcp --dport 80 -j =
REDIRECT --to-ports 3129

will match any ppp interface.

> You can also use -s "ip address" instead of -i  "name of interface".

or both...
