Somewhere along the way we broke supporting numbers in
the security group API that were not in our known list
of protocols. In order to fix this properly we must
use the correct arguments when using iptables-save, as
it could use a name instead of a number, or vice-versa.
Determined the list of mappings by doing:
for num in {0..255}; do iptables -A INPUT -p $num; done
# iptables-save
