3.62. NATPool

Description

A NAT Pool is used for NATing multiple concurrent connections to using different source IP addresses.

Properties

Name
Specifies a symbolic name for the NAT Pool. (Identifier)
Type
Specifies how NAT'ed connections are assigned a NAT IP address.
ExternalIPPool
Specifies the external IP addresses used for NAT translation. The total amount of IP addresses in the range(s) must be less than 65k.
InternalNetwork
Specifies the internal IP addresses used for Deterministic NAT translation. The total amount of IP addresses in the network must be less than 65k.
DynBlockAllocation
Specifies if IPs outside the internal address range are allowed to allocate dynamic blocks. (Default: InternalNetwork)
CompressionRatio
Specifies how many internal IPs will be mapped to each external IP. (Default: Auto)
DetBlockSize
Specifies the number of external ports in each pre-allocated deterministic port block. (Default: Auto)
DynPoolRatio
Specifies the percentage of available ports that will be used for dynamic port block allocation. Note that this percentage of available ports are always reserved for dynamic allocation. If set to 0, dynamic allocation is disabled. (Default: 0)
DynBlockSize
Specifies the size of each dynamic port block. (Default: Auto)
DynBlockAllocLimit
Specifies the number of dynamic port blocks allowed to be allocated for each internal IP. (Default: 1)
ReservedPorts
Ports from 1 to ReservedPorts will not be assigned in deterministic or dynamic blocks. (Default: 1023)
StateKeepAlive
The number of seconds that stateful NAT state will be kept in absence of new connections. (Default: 120)
MaxStates
Maximum number of states kept by this stateful NATPool. In general, one state is needed for each local host or client (internal IP) that will use the NAT pool. There is only one state table per NAT pool so that if a single pool is reused in multiple NAT IP rules, they share the same state table.
Comments
