Description
A SCTP Service is a definition of a SCTP 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.
- SourcePorts
- Specifies the source port or the port ranges applicable to this service. (Default: 0-65535)
- MaxOutboundStreams
- The configured value will be used to clamp the value for the number of Outbound Streams in an INIT chunk, and the value for
the number of Inbound Streams in an INIT ACK chunk. Does not affect the firewall performance in any way but end-points will
have to allocate kernel resources for every stream being negotiated, even when not in active use. (Default: 10)
- MaxInboundStreams
- The configured value will be used to clamp the value for the number of Inbound Streams in an INIT chunk, and the value for
the number of Outbound Streams in an INIT ACK chunk. Does not affect the firewall performance in any way but end-points will
have to allocate kernel resources for every stream being negotiated, even when not in active use. (Default: 10)
- MaxDataChunks
- The maximum allowed number of SCTP DATA chunks in each SCTP packet. Packets violating this are dropped. Can be set to 1 to
disable DATA chunk bundling support. The minimum size of a DATA chunk is 20 bytes (with padding), so it is possible to fit
about 70 chunks into a common 1500 byte network packet. More DATA chunks per packet will increase the cost of forwarding each
packet, but also makes better use of the network bandwidth than individual packets. (Default: 50)
- MaxControlChunks
- The maximum allowed number of SCTP control chunks in each SCTP packet. Packets violating this are dropped. (Default: 5)
- MaxSourceAddresses
- Maximum number of IP addresses an initiator of an association can use including the primary IP. IP addresses that exceed this
limit shall be stripped. The number of IP aliases have a profound effect on memory consumption. (Default: 2)
- MaxDestAddresses
- Maximum number of IP addresses a responder of an association can use including the primary IP. IP addresses that exceed this
limit shall be stripped. The number of IP aliases have a profound effect on memory consumption. (Default: 2)
- PPIDFiltering
- Specifies whether blacklisting or whitelisting should be considered for Payload Protocol Identifier (PPID) validation of an
SCTP DATA chunk. (Default: Blacklist)
- Whitelist
- Whitelist filter on Payload Protocol Identifier (PPID). If configured only DATA chunks with these PPIDs will be allowed. SCTP
associations carrying disallowed DATA chunks will be closed. Note: Whitelist and Blacklist are exclusive; Only one of them
can be configured at the same time. (Optional)
- Blacklist
- Blacklist filter on Payload Protocol Identifier (PPID). If configured, DATA chunks with these PPIDs will be disallowed, and
all others allowed. SCTP associations carrying disallowed DATA chunks will be closed. Note: Whitelist and Blacklist are exclusive;
Only one of them can be configured at the same time. For whitelist to be selectable blacklist must be disabled. (Optional)
- PassICMPReturn
- Enable passing an ICMP error message only if it is related to an existing connection using this service. (Default: No)
- AppProto
- Specifies the application protocol than controls what extended processing/validation that is available for traffic using this
service. (Optional)
- Comments
- Text describing the current object. (Optional)
