XGS Firewall DNS Request Route over SSL Site2Site VPN

Sebastian Christoph

Hello everyone.

I have 2 XGS Firewalls connected via SSL Site2Site VPN, which works good. I created a DNS Request Route for contoso.com (changed of course to my setup) to go to DC DNS IP in main office.

This worked for quite some time, now it does not. I experienced this behavior before on another setup and I'm unable to find any error.

IPs:

Site A - Site B

192.168.100.0/24 - 192.168.0.0/24

192.168.100.1 Sophos Site A - 192.168.0.1 Sophos Site B

DNS Request Route on Sophos Site A: contoso.com 192.168.0.10

192.168.100.1 as DNS on PC Site A. I can't get a ns lookup for dc.contoso.com.

If I put the DC DNS to PC the lookup works of course.......

Thank you and Best Regards!

    Hello Sebastian,

    Thank you for contacting the Sophos Community.

    How is the DNS configured in the PCs? What suffix are you adding?

    If the computer doesn't have a Suffix added for DNS, the NSlookup will fail because nothing will be attached to the lookup.
