This missing alias8 in the last line leads to alias_9-13 not being
configured, as the ... rather stupid way of counting up variables with
suffixes is very error prone and you may have just stepped into the trap.

alias9="172.19.4.41" would have been tools2's IP address but that never
was configured.

You should use the new ipv4_addrs_em0="172.19.4.32 172.19.4.36-39
172.19.4.41-48 ..." Makro to avoid those pitfalls.

This needs to be enabled, too.
