Hello Seyyed, 
 Thank you for contacting the Sophos Community. 
 Take a look at this https://support.sophos.com/support/s/article/KB-000035744?language=en_US 
 Additionally in your Cisco router, you might need to bridge the two ports g0/1 and g0/2 as the WAN interfaces should share the same IP on the XG. 
 If you need assistance with configurations or POC you can contact our Professional Services or your Sales engineer.
