Ip alias / load balance issue

[itzjustinn]

hello, i hope this is right section.

when i goto setup virtual server for load balancer i see that i am able to configure an ip alias rather than an ip.
further investigation showed me that i "should" be able to configure said alias with a fqdn that will resolve and that ip will be used.
when i attempted to use this configuration on my virtual server for the load balancer, relayd service stops running due to syntax error.
it appears that when i set ip manually, in the relayd config file i can see "listen on x.x.x.x port 80"
however when i set the alias, it shows "listen on port 80"
i am not sure if this is a bug or more likely i am not understanding something.
