Reference documentation and code samples for the Compute Engine v1 API enum SecurityPolicyUserDefinedField.Types.Base.
The base relative to which 'offset' is measured. Possible values are: - IPV4: Points to the beginning of the IPv4 header. - IPV6: Points to the beginning of the IPv6 header. - TCP: Points to the beginning of the TCP header, skipping over any IPv4 options or IPv6 extension headers. Not present for non-first fragments. - UDP: Points to the beginning of the UDP header, skipping over any IPv4 options or IPv6 extension headers. Not present for non-first fragments. required
