Severity: 5-Cosmetic


The SOCKS and HTTP Explicit Proxy profiles require a DNS Resolver. You must create the resolver before configuring the profile. You can create the resolver by navigating to Network :: DNS Resolvers in the GUI. Once the resolver is created, it appears in the list of DNS Resolvers when configuring the SOCKS or HTTP Explicit Proxy profiles.


If you do not create and specify a DNS Resolver, SOCKS and HTTP Explicit Proxy Profiles do not work.


This is new functionality with version 11.5.0.


You must create the resolver before attempting to create the SOCKS or Explicit Proxy profiles.

Fix Information

In this release, there is a button to add a DNS resolver directly in the SOCKS and HTTP Explicit profiles.
