Script Firewall com MAC e IP

Eu tenho um arquivo chamado mac.txt e dentro dele contem as linhas IP e MAC separados por ponto e virgula, ex:
192.168.0.10;F0:AF:FF:FE:FA:00

Meu script do firewall contem o seguinte:

#!/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

E acontece o erro :

iptables v1.4.3.1: Bad mac address "192.168.0.10"
Try `iptables -h' or 'iptables --help' for more information.
iptables v1.4.3.1: host/network `F0:AF:FF:FE:FA:00' not found
Try `iptables -h' or 'iptables --help' for more information.
iptables v1.4.3.1: Bad mac address "192.168.0.10"
Try `iptables -h' or 'iptables --help' for more information.
iptables v1.4.3.1: host/network `F0:ADF:FF:FE:FA:00' not found
Try `iptables -h' or 'iptables --help' for more information.

Ja tentei usar também WHILE mas o erro acontece. Ele está pegando as ASPAS no IP e o APOSTROFE (`) no MAC.

Há duas maneiras de você resolver este problema:

maneira 1:

mudar a sintaxe do cut para

MACSOURCE=`echo $i | cut -d \; -f1`

maneira 2:

substituir os ; no seu arquivo txt e mudar de cut para
MACSOURCE=`echo $i | awk '{ print $2}'`

Isto deve resolver.

Eu preciso que a saida do comando seja iptables -t filter -A FORWARD -d 0/0 -s $IPSOURCE -m mac --mac-source $MACSOURCE -j ACCEPT. (iptables -t filter-A FORWARD-d 0/0 -s 192.168.0.10 -m mac --mac-source 00:xx:yy:zz:99:88 -j ACCEPT).
Eu preciso do $IPSOURCE que está na primeira coluna e do $MACSOURCE da segunda coluna, Modifiquei o CUT para -d \; e deu o mesmo erro

Fiz o teste:

for i in `cat /root/mac.txt`;
do
MACSOURCE=`echo $i | cut -d ';' -f1`
IPSOURCE=`echo $i | cut -d ';' -f2`
echo $MACSOURCE
echo $IPSOURCE
done

e o script esta ok

Ficou assim e está funcionando :

>for i in `cat /root/mac.txt`;
>do
>IPSOURCE=`echo $i | cut -d \; -f1`
>MACSOURCE=`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

Obrigado pela ajuda
