    Hi,

    My MX5-T router shows the following for 'show chassis hardware':

     

    FPC 0                     BUILTIN      BUILTIN           MPC BUILTIN
      MIC 0                   BUILTIN      BUILTIN           4x 10GE XFP
        PIC 0                 BUILTIN      BUILTIN           4x 10GE XFP
    FPC 1                     BUILTIN      BUILTIN           MPC BUILTIN
      MIC 0          REV 27   750-028392   ABCE1123          3D 20x 1GE(LAN) SFP
        PIC 0                 BUILTIN      BUILTIN           10x 1GE(LAN) SFP
          Xcvr 9     REV 02   740-013111   8499509           SFP-T
        PIC 1                 BUILTIN      BUILTIN           10x 1GE(LAN) SFP
          Xcvr 0     REV 02   740-013111   E148735           SFP-T
    Fan Tray                                                 Fan Tray
    

     

    Is the above hardware protfolio sufficient for the router to do NAT/PAT?

     

     Thanks.

    Hi,

     


    You can use inline NAT. Please note, Only  Static NAT flavors are supported in inline NAT.

    PAT is currently not supported on MX5/10 without a Service MIC

     

    Note: Only static source NAT is supported. Port translation and dynamic NAT are not supported. An MS-MPC, MS-MIC, MS-DPC, or MS-PIC is still needed for any stateful-firewall processing and dynamic port translation
