here is my setup (firewall with 2 default routes) eth0 = cable, ppp0
adsl. I changed the dhcpd client to add the default route for each in
on a different metric, that way if the one of the lines is out the other
default route will still work!
from ip r (whith some stuff removed - but the essential stuff is here)
default metric 5
nexthop via 141.168.16.1 dev eth0 weight 4
nexthop via 202.7.162.89 dev ppp0 weight 2
default via 141.168.16.1 dev eth0 metric 10
default via 202.7.162.89 dev ppp0 metric 20
from ip ru
0: from all lookup local
200: from 141.168.16.16 lookup cable
201: from 60.240.81.237 lookup adsl
32766: from all lookup main
32767: from all lookup default
the important ones are 200, 201 these setup up the routing for each of
the different legs - cause they will be different! so 141.168.16.16 is
on eth0 and 60.240.81.237 is on ppp0 (they are the actual address on
the interfaces)
cat /etc/iproute2/rt_tables (these are where the names come from above!)
#
# reserved values
#
255 local
254 main
253 default
0 unspec
#
# local
#
#1 inr.ruhep
200 cable
201 adsl
These are the routing tables for 200 and 201, the 192.168 address are
the local address. The routing engine workes from the lowest numbered ru
(from ip ru ) and works to the larger numbered ones until it finds a
rule that matches!
# ip r sh tab 200
192.168.11.0/24 dev br0 scope link
192.168.10.0/24 dev eth3 scope link
192.168.9.0/24 dev eth4 scope link
default via 141.168.16.1 dev eth0
default via 141.168.16.1 dev eth0 metric 10
# ip r sh tab 201
192.168.11.0/24 dev br0 scope link
192.168.10.0/24 dev eth3 scope link
192.168.9.0/24 dev eth4 scope link
default via 202.7.162.89 dev ppp0
Hope that helps
