	My recommendation is to stick with the forward_shared
flag as method to solve the problem. Set it to 1 for the internal
interface connected to the real servers. Then it is safe to add the
VIP as normal IP address on some interface. Also, it is a bad idea to use
the forward_shared flag to allow spoofing from external interfaces.
