ipProtocol
The IP protocol name (tcp
, udp
, icmp
, icmpv6
) or number.
[VPC only] Use -1
to specify all protocols.
When authorizing security group rules, specifying -1
or a protocol number other than tcp
, udp
, icmp
, or icmpv6
allows traffic on all ports, regardless of any port range you specify.
For tcp
, udp
, and icmp
, you must specify a port range.
For icmpv6
, the port range is optional. If you omit the port range, traffic for all types and codes is allowed.
