Protocols
A network protocol is a set of communication rules agreed upon by endpoints (computers) for the
purpose of exchanging data.
The security gateway predefines the most commonly used protocols, including their ports and packet
types (TCP, UDP, IP, or ICMP). You can use these predefined protocols singly or in combination in
rules, but you cannot change or delete them.
You can also define additional custom protocols which may be necessary for custom applications.
To use a protocol with authorization rules, it must be associated with either an individual predefined
proxy or a Generic Service Proxy (GSP).
ICMP Based Protocol Properties—General tab
You use an Internet Control Message Protocol (ICMP) to send error and control messages about routing
problems or simple inter-network exchanges like time-stamp or echo transactions to verify
connections between TCP/IP hosts.
