Sophos Heartbeat - Make it work behind Firewall

Hey Mr.Roboto 

Here is the KB regarding which domains and ports are required for this communication.

Below is a screen capture of the default web exception on the Sophos XG for Sophos Services.

I hope this helps, please keep me updated.

Regards,

Good morning Flo,

thank you so much.

I knew that there was an entry but now it's confirmed. :)

So these exeptions are for "Live Connect" this means not only "Hearbeat"?

That is correct, those domains listed are used by the endpoint to communicate it's health (and other information) as part of the Heartbeat function.

And a last question:

Heartbeat still requires a non proxied connection to the Sophos servers, right?

I know that there is a option for enable proxy setting in central.

It is possible to utilize a proxy, take a look at this KB: How to allow Sophos Central Managed Endpoint, UTM Managed Endpoint, and Sophos Home to use proxy server settings

I'll try this in lab. In the last try it seems to work only if the following is given:

• Client can resolve sophos URLs
• Client has a route for public internet access points to XG

If the client has no route to the internet and can't resolve the DNS names, it will not work - so in my last try in the lab.

All of the other stuff of the endpoint software runs over the proxy without any issue.

Thanks for sharing that info! Please don't hesitate to reach out to me if your run into any further issues.
