Hi,

Im having a couple of problems in which my director has gone sour.

The interface with the internal ip seems to be arping for the vip, but since it does not have the vip attached to it, it does not accept the traffic send to it.

The routers in the network therefor cannot send the traffic to the VIP and broadcast the packet. Which results in the entire vlan answering that they are not the one to contact (or something similar), because the interface with the VIP attached to it also responds the packets in the end to wind up there, but it causes who lot of useless traffic.

Any suggestions?
Im using a Direct routing setup, and i have both the internal and extrnal interfaces connected to the same switch.

It had been running without many problems for 194 days now.

The ifconfig and route of the director are giving me the following:
