Filter action: IPv4/v6 decapsulate (IP-IP)

You can use a firewall filter over an IP-IP interface to de-encapsulate traffic, without the need to create any tunnel interfaces. IP-in-IP packets are special IP tunneling packets with no GRE header. With this feature, you can define a filter with filtering terms to classify packets based on packet fields such as destination IP address and protocol type. This feature provides significant benefits in terms of scalability, performance, and flexibility.
