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
