CGNAT APP+EIM+EIF is same as persistent-nat related to Full Con NAT

  • 1.  CGNAT APP+EIM+EIF is same as persistent-nat related to Full Con NAT

    Posted 28 days ago

    Hi,

    We are trying to set up full-cone NAT on an ISP SRX5K with SPC3, specifically for STUN/P2P applications.

    From our documenataion, it appears that Junos supports full-cone NAT using Persistent NAT, and also through a combination of Address Pooling Paired (APP), Endpoint-Independent Mapping (EIM), and Endpoint-Independent Filtering (EIF).

    We are trying to understand whether Persistent NAT and the combination of APP + EIM + EIF serve the same purpose, or if they differ.

    Also, which of the two would be the best solution in this scenario?
