GCP Packet Mirroring currently does not support negative filters supporting the “not” condition, e.g. not 10.0.0.0/8. To work around this and mirror only internet traffic, specify a filter that includes public CIDR blocks and excludes 10.0.0.0/8 internal traffic. IP ranges to use:128.0.0.0/1 64.0.0.0/2 32.0.0.0/3 16.0.0.0/4 0.0.0.0/5 12.0.0.0/6 8.0.0.0/7 11.0.0.0/8
NOTE: Each CIDR block needs to be added one by one for GCP to recognize it. The whole string above cannot be cut and pasted.
