Filter action: De-encapsulate IP-in-IP in input filter

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 provides significant benefits in terms of scalability, performance, and flexibility.
