Public bug reported:
Parts of the init script fail if the external interface has multiple IPs
assigned.
systemctl status output:
CGroup: /system.slice/miniupnpd.service

The problem is this line:
EXTIP="$(LC_ALL=C ${IP} addr show ${MiniUPnPd_EXTERNAL_INTERFACE} | grep "inet
" | awk '{ print $2 }' | cut -d"/" -f1)"
It should be changed to (preferably with another variable in
/etc/default/miniupnpd to override it):
EXTIP="$(LC_ALL=C ${IP} addr show ${MiniUPnPd_EXTERNAL_INTERFACE} | grep -m1
"inet " | awk '{ print $2 }' | cut -d"/" -f1)"
Or, according to the manpage it could be removed (to use the default address)
and leave a variable to override it.
-o address
address used to connect to the internet. default address of the
interface will be used if not specified.
