Also there are problems with arp, due wrong multipath route selection (if the decision is already made that the route should go the direct way, the route and not the interface route is choosen, depends on which route was first in the tree). And finally, there are problems when adding / deleteing routes. example that does not work: ifconfig em0 192.168.0.1/24 ifconfig em1 10.0.0.1/24 route add 10.0.0.0/24 192.168.0.2 example that currently works with 8.2: ifconfig em0 192.168.0.1/24 ifconfig em1 10.0.0.1/24 route add 172.16.0.0/24 192.168.0.2 route add 172.16.0.0/24 10.0.0.2 Kind regards, Ingo Flaschberger --168430090-1859668186-1302013430=:2152--
