Problem Description

Restricting DNS lookups on the ProxySG
You want to restrict DNS lookup

Resolution

The DNS lookup restriction list is a list of domain names that apply globally, regardless of policy layer definitions. Once a domain name is added to the list, DNS lookup requests do not occur for that domain name while policy is evaluated. To create or modify the DNS Lookup Restriction list:

  1. From the VPM menu bar, select Configuration > Set DNS Lookup Restrictions; the Set DNS lookup restrictions dialog appears. The default is None; no domain names are restricted.
  2. To restrict every domain name, select All.
  3. To add specific domain names, perform the following steps.
    1. Select Listed Host Patterns. This enables the Host Patterns field.
    2. Click Add; the Add Host Pattern dialog appears.
    3. Enter a domain name; click OK.
    4. Repeat to add other domain names.
    5. Click OK.
