Can´t reach Fritzbox webconsole behind Sophos XG

Hi,

i have a Sophos XG in gateway mode behind my Fritzbox. The setup is:

Fritzbox: 192.168.2.254 /30 it´s also the gateway and dns for the XG.

Sophos XG: WAN: 192.168.2.253 /30

Sophos XG: LAN: 192.168.2.252 /24  The Gateway for the LAN-Zone

Rule is the default network rule

My issue is, that i can´t reach the Fritzbox websonsole or ping the Fritzbox over the LAN-Zone. But when i connecting to my Wifi-Zone i can reach the Fritzbox.

Do you have any idea ? Thanks a lot
