Reverse DNS lookup on Sophos XG v18

dempie

Hi,

I am using Sohos XG, version SFOS 18.0.4 MR-4. It seems the way I configured DNS doesn't work for reverse DNS lookup of the firewall software itself. Please see attached screenshot.



My DNS configuration looks as follows:
-All clients use Sophos XG as DNS server.

-I have specified static DNS servers on Sophos XG.


-There are several DNS request routes for internal domains configured under Network DNS. One of them is 10.in-addr.arpa.



Reverse DNS lookup from clients are fine. But as I said, Sophos XG itself can't lookup internal IP addresses. It looks like these system requests are always forwared to configured static DNS servers regardless of DNS request routes.

Is it the expected behaviour on Sophos XG or is anything wrong with my configuration?

Thanks.

    Hi,

    to get reverse DNS working from the XG you will need to create every device in the XG DNS table or alternatively use an internal DNS and point the XG at it.
