Hello lists, Just for the archive records: we solved it this way (with the good help of IBM): # ip route add 10.0.24.0/24 dev eth1 proto kernel scope link src 10.0.24.xxx table 1 # ip route add default via 10.0.24.1 dev eth1 table 1 # ip rule add from 10.0.24.xxx/32 table 1 priority 500 # ip route flush cache Which is now run at bootup on the affected servers, giving us the solve we need. Thanks everyone who replied. Jan -- Auribus teneo lupum. [I hold a wolf by the ears.] [Boy, it *sounds* good. But what does it *mean*?] - : send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
