Is there any other way of blocking IP proto 0 packets?
You could use a default-deny/drop rule set, i.e. only allow the stuff
you need (probably inet and inet6).
Hmm, it looks like IP-in-IP packets are blocked by default. See
sysctl(3) about net.inet.ipip.allow.
Ah, good news indeed! Many thanks, I never would have spotted that.
Cheers
