Environment

Cause


  • The issue is due to DNS configuration.
  • The network DNS server is not picked up by iOS device when GlobalProtect is connected.
  • No DNS servers are specified in gateway configuration.

Resolution


  1. Configure DNS servers in the gateway configuration.
  2. This is configured at GUI: Network > GlobalProtect > Gateways > [gateway-name] > Agent > Network Services 
  3. Once configured, reconnect the client to GlobalProtect and the browsing will work fine.
