Do I need DNS entries in both Windows server, and Sophos UTM?

ryanmc

Hey guys,

 

I am a home user of Sophos UTM and I have what is probably a basic networking question. I am trying to setup #3 in the DNS Best Practices but I seem to be duplicating work. I have already setup DNS entries in Sophos for each of my devices in the Network Definitions tab. But for the reverse lookup to work it seems like I am having to do it again when I create the reverse lookup zone and PTR records in Windows server. Does this seem correct? Is there anyway to get Sophos to export the DNS records to Windows server or something so I don't have to maintain these in two locations, or so I don't mistype a name or IP and mess it up?

 

Also when I do a nslookup it does not display the name of the computer

 

C:\Users\joe>nslookup 101.0.168.192.in-addr.arpa
Server: home-server.mydomain.local
Address: 192.168.0.104

Name: 101.0.168.192.in-addr.arpa

 

Thanks

    I would say Sophos.

    I mainly use Windows Server as a replacement for Window Home Server, so it is glorified File host and backup system. However during the install it required setting up a domain. Also when I add a new computer to backup it also adds it as a client to the server. I only have 5 computers added to the domain and doing backups, the rest of my computers and devices are just hanging out on the network. Whenever I add a new phone or tablet, or any other device that I don't want backups of I just use Sophos and never touch Windows server.

    I hope this help explain things.

    So you basically have 2 DNS zones, one for your Windows Server and one in the UTM.

    My suggestion would be, Set ALL your devices to use the Windows Server DNS.

    On Windows set the DNS forwarders to your UTM.

     

    So DNS would go, Device > Windows Server > UTM > Internet

     

    This would allow all devices to have the correct DNS and reverse DNS records on the Windows server, and your lookups would work.
