Publish some web applications using the same public IP.

Question

Hello friends. 
 I only have one public IP on my Sophos XGS, but I want to publish three web applications (web1.dominio.com, web2.dominio.com, web3.dominio.com), all arriving on the same public IP and on the https port. 
 I know that via NAT, this would only be possible using other public IPs, creating alias on the WAN interface. 
 But as I only have a public IP, can I somehow do this? Could the WAF be the solution? 
 Thanks !

Yes, this can be easily done using WAF in Sophos XG. But make sure you select the Pass host header in your WAF Business Application rule.

Please refer to this KBA Sophos XG Firewall: WAF configuration guide and in case if you need there's a Sophos XG Firewall: WAF Troubleshooting guide as well.
