QuestionQ15

Advanced Network Address Translation (NAT)

A user reports that a particular application is not functioning properly. The application creates multiple connections to the server and must use the same address every time. The firewall assigns several different source addresses from a pool, and this behavior must be changed.

What would resolve this problem?

  • A Use the persistent-nat parameter.
  • B Use STUN.
  • C Use the address-persistent parameter.
  • D Use DNS doctoring.
Explanation

The Junos source NAT address-persistent option assigns a host the same statically chosen translated IP address from a source NAT pool across multiple sessions, satisfying applications that require a consistent source address.
