About AFM NAT Translation Objects
AFM NAT translation objects
AFM NAT source translation objects
A unique name for the source translation.
Specifies descriptive text that identifies the source translation item.
Specifies the translation source IPv4 or IPv6 addresses available for allocation. All public source addresses come from this pool of IP address subnets.
Specifies the translation source service port or range of service ports available for allocation. All public source ports come from this pool of service ports. This option is not available when Static-NAT is the selected translation mode.
Enables or disables responses to ICMP Echo requests for translated source IP addresses.
Specifies whether AFM responds to ARP requests for translated source IP addresses.
Specifies whether AFM advertises routes for translated source IP addresses using the BIG-IP system's advanced routing modules (enabled), or not (disabled).
Lists interfaces over which source translation may or may not be allowed.
AFM Dynamic PAT options
Specifies which type of translation mapping is performed. Available options are:
Port Block Allocation options
These options are available when
PAT Modeis set to
Port Block Allocation.
PAT Modeis set to
Deterministic. Specify additional backup addresses that may be used as translation addresses if DNAT mode fails deterministic translation. When this occurs, the fallback type is set to NAPT mode.
Specifies the set of addresses excluded from translation IP addresses available in the pool.
Specifies the mapping mode for persisting translation entries, or how to preserve public IP addresses for clients from session to session. Available options are:
Specifies the mapping timeout period after the most-recent session where address:port X:x translated to X':x' on the public side, a timer begins. If the timer expires before X:x has another session, X' or x' may be used as the public side of another address:port. Use this parameter to set the timeout in seconds for addre
Modifies the inbound-connection mode for incoming connections to translation endpoints. A translation endpoint is the public-side address and port (X':x') for a private-side address (X:x). You can enable the following algorithms for managing inbound co
Client Connection Limit
This is the maximum number of simultaneous translated connections a client or subscriber is allowed to have.
Enables or disables hairpinning for incoming connections. When a client sends a packet to another client in the same private network, hairpin mode sends the packet directly to the destination client's private address. The BIG-IP system immediately translates the packet's public-side destination address. Rather than going out to the public network and returning later for translation, the packet takes a
hairpin turnat the BIG-IP device.
NAT Stats Profile
Associate a NAT stats profile.
A Port Control Protocol (PCP) client can set, or learn, its translated public-side IP address and service port. It can also set the IP address and service port of a third-party client. PCP is defined in RFC 6887. Available options are:
AFM destination translation objects
A unique name for the destination translation.
Specifies descriptive text that identifies the destination translation item.
Specifies the type of destination translation to use. The available options are:
Specifies the translation IPv4 or IPv6 addresses available for client allocation. This is a list of IP addresses and their subnet lengths. All addresses come from these IP address subnets.
Specifies service port or range of service ports used for destination translation. This option is not available when
