Updating the Tunnel Endpoint

For a dynamic WAN, such as DHCP or PPPoE, HE.net can still be used as a tunnel broker. AZTCO-FW includes a DynDNS type that will update the tunnel endpoint IP address whenever the WAN interface IP changes.

If DynDNS is desired, it may be configured as follows:

• Navigate to Services > DynDNS
• Click + Add to add a new entry.
• Set the Service Type to be HE.net Tunnelbroker.
• Select WAN as the Interface to Monitor.
• Enter the Tunnel ID from the tunnel broker configuration into the Hostname field.
• Enter the Username for the tunnel broker site.
• Enter either the Password or Update Key for the tunnel broker site into the Password field.
• Enter a Description.
• Click Save and Force Update.

If and when the WAN IP address changes, AZTCO-FW will automatically update the tunnel broker.
