Sophos XG Firewall WAN Link cannot auto update

Question

In case I use the router, configure it in bridge mode and connect to a firewall that accepts IP on the WAN as DHCP, which if the router has updated the IP but the WAN pin is still the original IP address, not exactly how to configure it. To keep the WAN link updated and I have found a box, select Schedule for reconnecting, which means it's necessary to select Yes or No.

Hello Kitti, 
 Thank you for the follow-up! 
 Oh for PPPoE, it is optional, but here is the info on what that option does exactly: 
 Schedule time for reconnect: The address assigned to a PPPoE connection, whether dynamic or static (preferred), can have a predefined validity period. Once the validity expires, the PPPoE connection is terminated and is reconnected. To prevent reconnection during working hours, enable the PPPoE reconnect schedule. 
 On reconnection, an address other than the preferred IP address (if specified) may be assigned to the PPPoE connection. 
 Regards,
