Dynamic WAN IP With IPSec Site to Site

The client has a Sophos XGS107 in the branch office and an XGS2100 in the head office. We have site-to-site IPSec with PSK with HO to 2 BO.

Due to the PPPoE WAN IP provided by the ISP, the firewall’s WAN interface IP changes frequently. We face a challenge each time the WAN IP changes, as we need to edit the IPSec VPN setup on the firewall to restore the site-to-site connection.

In the above scenario, what would be the best solution to resolve the issue permanently? Could Dynamic DNS be a solution? Have you implemented it with Sophos?
