Hi guys

I need help getting my iptables script to run on my RedHat 7.3 box.
The script is as follows

Code:
#!/bin/bash
./iptables -A INPUT -p udp --dport 68 -j REJECT
./iptables -A INPUT -p udp --dport 1025 -j REJECT
./iptables -A INPUT -p udp --dport 111 -j REJECT
./iptables -A INPUT -p udp --dport 1024 -j REJECT
./iptables -A INPUT -p tcp --dport 25 -j REJECT
./iptables -A INPUT -p tcp --dport 111 -j REJECT
./iptables -A INPUT -p tcp --dport 1024 -j REJECT
./iptables -A INPUT -p tcp --dport 1025 -j REJECT
./iptables -A INPUT -p tcp --dport 6000 -j REJECT
which is in /sbin, but when i run the script and do a scan on myself the ports are still open!
Ive tried typing iptables -V but i get 'command not found' which i think means that iptables is not loaded.
Ive also tried ipchains -V which gives me the same message so that isnt loaded!

I dont know what else to do so any help would be great!

Cheers
