Hi,
Configuration example:
So if you would have 2 Virtual Server on the same IP,
just with different Source Filters.
Let’s say
VS-1 10.10.10.10:443 Source 192.168.0.0/16
and
VS-2 10.10.10.10:443 Source 0.0.0.0.0/0
Both with SSL/TLS and HTTP profiles
Question
1)
So if VS-1 is down based on no Pool members or Disabled
by an F5 Admin. traffic from 192.168.0.0/16 would get a TCP RST from VS-1 and
never hit VS-2?
2)
will an irule using "virtual" work in this case? or is there an other irule funktion that would do this?

when FLOW_INIT {
if { [active_members testpool] < 1 } {
virtual VS-2
}
}
