Sophos Firewall specific IP's cannot be found via VPN.

Hello Together

We currently have a problem with the VPN. We have two Sophos XG 125w which are connected via VPN. The VPN rules have been created. From external via VPN I can access the internal LAN. Only certain Ips I can not ping. I have already tried to disable the Windows firewalls on the devices. Unfortunately, this has brought nothing. Internally I can ping the IP addresses without problems. Does anyone have an idea?

Thanks a lot
