My use case is that users connect to IPv6 addresses managed by
keepalived for relay'ing SMTP, and then outgoing connections are
coming from the keepalived managed addresses instead if the "host"
address. This is causing problems for our mail-servers speaking
with gmail (which requires matching AAAA and PTR records, and PTR 
should ideally identify the real host initiating the communication),
and it's also making it difficult to know which IPv6 addresses to
open for our hosts to do communication with other systems.
Normally we would expect to use the "host" address, but now we
need to open both the "host" address, and any other keepalived 
managed IPv6 addresses to cover all possible sources. Not ideal.
