Hi, You should change your last rule for some as it: ip route add equalize default nexthop via 192.168.1.1 dev eth0 nexthop via 201.81.219.1 dev eth2 It works fine for load balancing, but when a failure occurrs on one line, whats happen? if one line is down the change it is too slow, and the cache for the route is still there and when I want this Host again the old route is through from the "down" line. I have a script which runs via ping and cron when next hop is down, the box linux will change to use one line.
