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 > > --gypsy > _______________________________________________ > LARTC mailing list > LARTC@xxxxxxxxxxxxxxx > http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc >
