Hello Ruben, 
 Thank you for contacting the Sophos Community. 
 I'd recommend you to reach to your Sales Engineer, or Professional Services, for hybrid setups. 
 As of your questions, 
 1. It would be the Public IP of FQDN where Central will be sending the email to, which is usually the Public IP of your router, protecting your exchange server. In the case of being a O365 it would be the server name that O365 provides you with <yourdomain-com>.mail.protection.outlook.com 
 2. This is the IPs for outbound email from your organization, where Central expects traffic to come from, usually the Public IP of your router. 
 Regards,
