"rule": "FROM all vms TO IP 255.255.255.255/32 BLOCK udp PORTS 1-65535",
gives

Isn't there supposed to be a netmask? "/32" for 255.255.255.255.
Shooting from the hip (and I have no way of testing right now):
FROM all vms TO IP 255.255.255.255/32 BLOCK udp PORTS 1-65535

Hi!
From any VM one can generate UDP broadcasts:
# socat - UDP-DATAGRAM:255.255.255.255:24000,broadcast
How do I stop a vm from emitting UDP broadcasts? Firewalling to IP
255.255.255.255 does not work:
"rule": "FROM all vms TO IP 255.255.255.255 BLOCK udp PORTS
1-65535",
# fwadm add -f stop-udp-bcast
IPv4 address "255.255.255.255" is invalid
Kind Regards,
Stefan
