Hi,

Thanks to all in advance,

In recent I need policy based routing on my Linux2.4.3 box. requirement is like to give access of Internet to some computers while this facility is not available to rest people (That is based on MAC address only).

My existin routing in "table main" is...

192.168.1.0/26 dev eth0  proto kernel  scope link  src 192.168.1.3 
192.168.1.64/26 dev eth1  proto kernel  scope link  src 192.168.1.65 
192.168.2.0/24 via 192.168.1.2 dev eth0 
127.0.0.0/8 dev lo  scope link 
default via 192.168.1.1 dev eth0 

Where 192.168.1.1 is ip of router, there is no restriction required on 192.168.1.0/26, while on 192.168.1.64/26 I need to give access to some computers only.

I have done some work on it but not get success. I have done like

#iptables -A PREROUTING -t mangle -i eth1 -m mac --mac-source ab:cd:ef:12:34:56 -j MARK --set-mark 1
#ip rule add fwmark 1 table John
#ip route add unreachable default table John

Then after I have tried in INPUT too.. But no success.

If any one have implemented in their network Please guide me. What basic mistakes I am commiting in this scenario?

Looking forward for kind reply from Network Gurus.

Thanks and regards
Bharat Merja.
