Configuration Sophos XG mode inline

Question

Good morning, everyone, 
 I would like some information on how to configure and attack the Sophos XG firewall that I just bought inline with a Watchguard firewall. 
 1. Do I have to do any particular configuration inside to make it work in this mode? 2. In which ports should I attack the Watchguard firewall and then where should I put the cable to connect it to the switch. 
 If you have other information are welcome. 
 
 Thank you very much.

Hi Jacopo Sandri1 
 Please first take a look at the following article: Sophos XG Firewall: How to deploy in bridge mode 
 In regards, to your 3rd party firewall that you have in-line with the Sophos XG, this would depend on your network configuration. I would advise to speak with your Sophos Partner/Reseller to get in contact with our Professional Services team for your initial setup.
