[Resolved]:UTM 9 IPSec VPN can't resolve DNS internal hostnames

Hello,

using a UTM 9.

VPNSSL connections from Sophos connect are configured and worked well.

I create a VPN IPSec connection always from Sophos connect.

The connection establish, I can see in the Sophos connect client the DNS and the domain name suffix configured in the UTM.

I can ping the network allowed in the UTM, put I can't resolve the internal hostname with or without domaine name suffix.

If I lookup a internal hostname, the DNS server is our internal DNS server configured, but it times out.

So why the VPNSSL can resolv internal hostname and not VPN IPSec ?

Thank's.

Regards.

Fred.
