firewall script with MAC and IP
I have a file called mac.txt and inside it contains the following: IP and MAC,
192.168.0.10;F0:AF:FF:FE:FA:00
My script for firewall is as follows:
#!/bin/bash
for i in `cat /root/mac1.txt`;
do
MACSOURCE=`echo $i | cut -d ';' -f1`
IPSOURCE=`echo $i | cut -d ';' -f2`
iptables -t filter -A FORWARD -d 0/0 -s $IPSOURCE -m mac --mac-source $MACSOURCE -j ACCEPT
iptables -t filter -A FORWARD -d $IPSOURCE -s 0/0 -j ACCEPT
iptables -t filter -A INPUT -s $IPSOURCE -d 0/0 -m mac --mac-source $MACSOURCE -j ACCEPT
iptables -t nat -A POSTROUTING -s $IPSOURCE -o eth0 -j MASQUERADE
done
