A much better option than suid-ing a script IMO is to use sudo to give your user exactly the capabilities he needs. For example, if you put this in your /etc/sudoers file:

nobody: ALL=(ALL) NOPASSWD:/sbin/iptables

Your user nobody will be able to call sudo iptables and it will execute as root without the need to enter a password. Personally this would not be quite paranoid enough for me, I'd prefer to write separate shell scripts which execute exactly the iptables command I want the user to be able to execute and specify these explicitly in sudoers, but YMMV.
