Transport layer protocol

A transport layer protocol provides end-to-end communication on top of the network layer (IP) layer for IP networks.

Using a FortiGate, you can create security policies that control the following transport layer protocols:  TCP (protocol number 6), UDP (protocol number 17), ICMP (protocol number 1), and SCTP (protocol number 132).
