VPN Site to Site - Fortigate x Sophos

I have two firewalls.
At one end a firewall with a dedicated link and at the other a Sophos firewall with dynamic IP.

I will have to increase the Dialup Type configuration.

Does anyone have any documentation that covers this type of configuration.
The biggest problem is at the Sophos end, I've already tried several ways.
But without success, I've seen several ways on the web but without success.

If anyone can give me some direction, I'd be grateful.

This guide is for s2s between FG and Sophos.

In your case you just need to change FG IPsec Remote GW type from Static IP to Dialup.
