Hi list

I have just a added a few rules to my routing table.

Would someone be so kind as to see if my setup is correct.

My setup is as so

eth0
IP 196.36.10.114
GW 196.36.10.113 (my routers IP)

eth1 192.168.111.10
PRIVATE LAN

eth2
IP 192.168.10.200
GW 192.168.10.100 (my adsl modem)

Please keep in mind that my router that is connected to eth0 has a static ip, where as my adsl modem that is connected to eth2 is dynamically assigned.

echo 200 IS >> /etc/iproute2/rt_tables
echo 201 TELKOM >> /etc/iproute2/rt_tables

/sbin/ip route add 196.36.10.0 dev eth0 src 196.36.10.114 table IS
/sbin/ip route add default via 196.36.10.113 table IS

/sbin/ip route add 192.168.10.0 dev eth2 src 192.168.10.100 table TELKOM
/sbin/ip route add default via 192.168.10.100 table TELKOM

/sbin/ip route add 196.36.10.0 dev eth0 src 196.36.10.114
/sbin/ip route add 192.168.10.0 dev eth2 src 192.168.10.100

/sbin/ip route add default via 196.36.10.113

/sbin/ip rule add from 196.36.10.114 table IS
/sbin/ip rule add from 192.168.10.100 table TELKOM

 From my routing table all seem ok:
gate:~# route -n
Kernel IP routing table

192.168.111.0   0.0.0.0         255.255.255.0   U     0      0        0 eth1
192.168.10.0    0.0.0.0         255.255.255.0   U     0      0        0 eth2
0.0.0.0         196.36.10.113   0.0.0.0         UG    0      0        0 eth0
gate:~#

If anyone has any tips or advise they would care to add, it would be most appreciated.

Kind Regards
