We have two clusters doing IPIP tunnelling.
This morning one failed. Ethereal shows incoming packets for the VIP
interfaces on both directors.
The failing director, however gives no [ACK] response. Any ideas on why
this would happen?
The network interface on the failing director is:

We don't see any incoming packets on the VIP interface of the real
server with the broken director ... why would the failing director not
show [ACK] responses?
