iptables based on mac address

[shadha]

Hello all,

   Its very urgent.My requirement is,I want to redirect a denied user to
some server(ex,172.16.1.111:1025 at which apache server runs)and the
allowed(accepted user) to the origin server based on  "mac"  address.

So I've setup the following 1st two rules  .
To allow particular user (00:00:00:00:00:01) I've setup  the 1st rule.
2nd rule is for redirecting all other users (except allowed user) to
server(where apache runs).

But what happened is it redirects all users to the apache server(including
allowed user 00:00:00:00:00:01,who want to access the origin server) .

1. /sbin/iptables -A FORWARD -p tcp --dport 80  -m mac --mac-source
00:00:00:00:00:01 -j ACCEPT
2. /sbin/iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to
172.16.1.111:1025

     Plz Specify where I've done a mistake.

3rd rule is for Redirect .

3. /sbin/iptables -A FORWARD -p tcp --dport 80 -j REDIRECT --to
172.16.1.111:1025

when executing this,error came like

[root@iptab kak]# sh test
iptables: Invalid argument

For 3rd rule ,how to overcome above specified error.

I request you all to reply as soon as possible.

Thanks in advance,
-shadha.
