  • 1.  SRX3600 Cluster Source NAT - Maximum port translations for 1 IP in NAT Pool

    Posted 09-24-2014 10:00

    Hello SRX NAT gurus.

    I am wondering how can I tell what is the maximum number of Single Port translations for a source nat pool configured with 1 IP.  For some reason, I believe I am only getting 31232 max - which is about half of 62463 (the number of ports available between 1024 and 63487 - which is the port range that is indicated that is available.

     

    Ex:

    > ...at source pool Test_Source_NAT node 1   
    node1:
    --------------------------------------------------------------------------
     
    Pool name          : Test_Source_NAT
    Pool id            : 7
    Routing instance   : Test-VR
    Host address base  : 0.0.0.0
    Port               : [1024, 63487]
    port overloading   : 1
    Total addresses    : 1
    Translation hits   : 4196678
    Address range                        Single Ports   Twin Ports 
          1.1.1.1 - 1.1.1.1                    31232             0   

     

    I think this has something to do with the cluster configuration, but am not sure.

    any guidance or direction would be helpful.  Thanks 🙂

    The KB article that i posted in my last response is now veiwable.  When clustered there are only 1/2 of the NAT ports available
