Description

Using "pfSense-CE-2.5.0-DEVELOPMENT-amd64-20200123-1059.iso" for a fresh install on a VirtualBox VM my configured VIP's are can only be pinged for a second or two during bootup.. (firewall does allow icmp..) Traced it down to the fact that running the same ifconfig command twice makes the ip-alias disappear from the nic! See below with a 'new' IP 192.168.0.234 that wasn't configured before.

Below em0 is a real nic that is 'bridged' to the Vbox-VM.. However the same effect happens for em1 which is configured as 'internal network' in the VM configuration so that one would certainly not depend on the real nic used..

Also just a 'ifconfig down'/'ifconfig up' makes the primary ip of the interface that is configured by dhcp disapear to never come back until a reboot is done..

What can be done to diagnose this further? (As the issue seems to come from the 'binaries' / kernel.. My php reading skills don't really help anymore.. and my C skills are pretty much nonexistent..)
