Description

A TCP/UDP Service is a definition of an TCP or UDP protocol with specific parameters.

Properties

Name
Specifies a symbolic name for the service. (Identifier)
DestinationPorts
Specifies the destination port or the port ranges applicable to this service.
Type
Specifies whether this service uses the TCP or UDP protocol or both. (Default: TCP)
SourcePorts
Specifies the source port or the port ranges applicable to this service. (Default: 0-65535)
SYNRelay
Enable SYN flood protection (SYN Relay). (Default: No)
Protocol
Protocol settings are only used by IP Policies. (Optional)
MaxSessionsProtocol
Specifies how many concurrent sessions that are permitted using this Protocol. (Default: 2000)
ForwardICMPErrors
Allow ICMP errors for active connections to be forwarded through the system. (Default: No)
EnableIPv4PathMTUDiscovery
Path MTU Discovery allows communicating endpoints to negotiate optimal packet sizes. This prevents fragmentation by network equipment between the endpoints. Path MTU Discovery relies on ICMP message forwarding so ICMP forwarding must also be enabled. (Default: No)
ALG
An Application Layer Gateway (ALG), capable of managing advanced protocols, can be specified for this service. (Optional)
MaxSessions
Specifies how many concurrent sessions that are permitted using this service. (Default: 200)
UseCustomTimeouts
Use Custom Timeouts. (Default: No)
InitialTimeout
Time in seconds of how long an partially established TCP connection (during SYN and SYN+ACK phase), or an established UDP or ICMP connection, is allowed to be idle. Default: 60 seconds. (Optional)
EstablishTimeout
Time in seconds of how long an established TCP connection is allowed to idle before being closed. Default: 262144 seconds. (Optional)
ClosingTimeout
