2. Configuring destination NAT rule

 

Instant 3.2 supports Destination NAT rule in ACL. Destination NAT rule is used to direct the traffic to  a specific destination irrespective of the original destination that the traffic was intended for.
One common usage scenario of this feature is sending all DNS requests to a third-party DNS server.
For example, OpenDNS servers provide misspelling correction, phishing protection, and optional content filtering Service.  If we add a rule:
 
rule any any match udp 53 53 dst-nat ip 8.8.8.8 53
 
IAP will rewrite the destination IP of all DNS queries to 8.8.8.8 regardless of the DNS server configured on the client.  This allows a customer to control client behavior.

 

 

Environment : This article applies to all the IAPs running 6.2.0.0_3.2.0.
