Bridge interface limited to 10MBit/s

Question

Hello everyone! 
 I installed Sophos XG Firewall (Home version) in bridge mode as I don't want to have 2 separate networks. 
 I host the File Station service on my Synology NAS for which I configured a business rule. I can reach the service but I'm limited to 10MBit/s from outside (WAN). 
 From the inside, everything works fine (1Gb/s). I saw that my bridge interface (br0) is limited to 10MBit/s. So, as my interfaces are under this bridge interface (picture), the speed is limited to 10MBit/s for every service from the outside. (LAG_BAIE is the 2Gb/s link to my Synology NAS). 
 I hope someone can help me, I have already spent a lot of time trying to fix the problem. 
 Thank you for your help. 
 Florian.

Hi KingChris, 
 I spent a whole day on the problem and ended up installing Sophos XG 18 EAP 3. Now, the limitation problem is gone. I think the problem came from the ports themselves, as you can see on the main post picture, I changed the order of the WAN and LAN ports to 1 and 2 respectively. For me, this is the source of the problem, and the only solution is to reinstall Sophos completely. 
 Now I'm looking for the WAF, I don't find the option on the new interface, but this is something else ;) 
 Thank you for your help.
