Doorbird connected to SOPHOS XG

We want to use a Doorbird (https://www.doorbird.com/de/) doorbell video station, connected to the SOPHOS XG via PoE.
We have created a firewall rule for the Doorbird's IP (Allow all Traffic, LAN to WAN).
Nevertheless, we do not receive any push notifications from the doorbell.
We only get a sound when the app is open on the iPhone, but also no push message.
The bell system is also not marked as online on the manufacturer's side (https://www.doorbird.com/checkonline).
As a test, we connected the system directly to the router via a PoE adapter.
Everything then works and the manufacturer also lists the system as online.
So something is still being blocked by the XG.
Does anyone have any ideas? We found a forum post here that deals with the same problem, but with a UTM (https://community.sophos.com/utm-firewall/f/german-forum/113368/doorbird/406180).

Thanks!

Hi Edvvde,

Thank you for reaching out to the Community!

Did you configure web filtering on your firewall? If yes, it could be the web filtering causing this issue.

Try to create a new firewall for the Doorbird's IP address in the source network, and then don’t apply any advanced filtering on the firewall rule.

Thanks,

Hi thanks for your answer. No, there is no configured web filtering for the LAN to WAN rule

Hi Edvvde,

Thank you for the update.

Did you configure DoS protection for UDP?

I would suggest you run a packet capture on the source IP address and check if the source's traffic is allowed or dropped by the firewall.

Check out the following KBA for more info: Monitor traffic using Packet Capture Utility in the Sophos XG Firewall GUI.

Thanks,

Hi ,

No, DoS protection for UDP is not configured. We ran a packet capture on the source IP.

But it looks like that the manufacturer's server can be accessed via TCP.

Hello There,

Take a look at this Community Post, you might need to create a custom SSL/TLS rule.
