[EC2-VPC only] Removes one or more egress rules from a security group for EC2-VPC. This action doesn't apply to security groups for use in EC2-Classic. To remove a rule, the values that you specify (for example, ports) must match the existing rule's values exactly.

Each rule consists of the protocol and the IPv4 or IPv6 CIDR range or source security group. For the TCP and UDP protocols, you must also specify the destination port or range of ports. For the ICMP protocol, you must also specify the ICMP type and code. If the security group rule has a description, you do not have to specify the description to revoke the rule.

Rule changes are propagated to instances within the security group as quickly as possible. However, a small delay might occur.


For .NET Core and PCL this operation is only available in asynchronous form. Please refer to RevokeSecurityGroupEgressAsync.
