I have a dhcp relay set up for my inside interface. I also have subinterface on another interface in routed mode that is on a separate security zone and separate network that also needs to point to the same dhcp relay server. On an old pair of ASAa I have no problem setting this up. On FDM gui I am restricted from having two set up pointing the dhcp server. Is there a way to go about this?
I'm running a pair of csf1230s in HA running FDM.
I also notice the HA mode always gives me the interface cannot be turned off because it's monitoring mode for HA. I often have to suspend and then break the HA to make changes. Is there a way around this? Why can't I easily turn off an interface?
