Hello All,

I have a linux box with advanced routing enabled.

I have two NIC one connected to LAN and another connected to two different
ISPs router.
Even in LAN interface i have two ip address that get packet from two
different network.

LAN1 has ip address in 172.16.1.0/32 and LAN2 has ipaddress in 172.16.5.0/32
so i asigned 172.16.1.1 and aliase as 172.16.5.1 in linux box LAN interface
and in internet interface 10.3.3.5 and aliase as 192.1.157.34.

I want LAN1 users go through 10.3.3.5 and LAN2 user go through 192.1.157.34

I set default gw as 10.3.3.6 in eth1.

and policy route as
echo 200 suresh >> /etc/iproute2/rt_tables
ip rule add from 172.16.1.0/32 table suresh
ip rule ls
0:      from all lookup local
32765:  from 172.16.1.0/32 lookup suresh
32766:  from all lookup main
32767:  from all lookup default

ip route add default via 192.1.157.35 dev eth1 table suresh
ip route flush cache

My problem i can communicate from LAN2 but i can not communicate from LAN1
where i set policy routing.

Do i need some more configuration in Advanced routing and
Should i need to use iptables for masquerading

Thanks
Suresh
