Configuring Advanced L2TP Settings

1. Open the Remote Access > L2TP over IPsec > Debug tab.

   The options on this page control how much debug output is generated in the log file. Select relevant options if you encounter connection problems and need detailed information about the negotiation of client parameters.

   In the IKE Debugging section, there are the following options available:

   • Control Flow: Displays control messages of IKE state
   • Outbound Packets: Displays content of outgoing IKE messages
   • Inbound Packets: Displays content of incoming IKE messages
   • Kernel Messaging: Displays communication messages with the Kernel
   • High Availability: Displays communication with other HA nodes

   In the L2TP Debugging section, if you select Enable debug mode, the IPsec VPN log file contains extended information about L2TP or PPP connection negotiation.

2. Click Apply to save your settings.

3. Open the Remote Access > Advanced page.

   This page allows you to define name servers (DNS and WINS) and the name service domain, which should be assigned to hosts during the connection establishment.

4. Click Apply to save your settings.
