I am new to Sophos/Astaro and working on configuring Sophos Home UTM
for the first time on my home network. So far, I am successfully using the
DHCP server to assign static IP addresses to most devices based on
their MAC addresses, with a handful of dynamic IP addresses set aside
for guest devices. But there's one aspect of it that isn't working
the way I'd like.
I would like the hostnames of the static IP devices to be resolvable
within the home network. That is, if I browse with Windows Explorer
to \LivingRoom or do 'ping LivingRoom' in a command prompt window, it
should resolve the name "LivingRoom" successfully to the IP address.
I do not have a separate DNS server or domain controller set up. I am
hoping that Sophos Home UTM alone can do this.
The assignment of IP's to devices is working, and if I ping/browse the
IP address for LivingRoom, it works fine.
I am seeing different behaviors for IP-> name resolution depending on
whether the client is a Windows PC or another device (e.g. webcam,
router, Roku)
For a Windows client, if I ping the hostname, it responds, but with
what looks like an IPv6 address response, rather than the IPv4
addresses assigned to it (although pinging the IPv4 address does also
work):
C:\>ping livingroom

Using Windows Explorer to browse to \livingroom seems to wrok.
For a non-Windows client, the hostname does not resolve, although the
IPv4 address assigned to the device does respond.
C:\>ping roku
Ping request could not find host roku. Please check the name and try again.
C:\>ping 192.168.1.206
Pinging 192.168.1.206 with 32 bytes of data:

In both Windows and non-Windows cases, I have configured the network
definition of the host along the lines of:
Name: roku
Type: Host
IpV4 Address: 192.168.1.206
DHCP Settings
IPv4 DHCP: Internal
Mac Addresses:
DNS Settings
Hostname: roku
Reverse DNS: checked
Please note that although I've used a Roku as an example, the same
behavior is seen with any non-Windows PC client, including an HP
printer, webcams, Chromecast, wireless routers, smartphones, IP
connected appliances like TV's, etc.
Can anyone get me pointed in the right direction?
Thanks,
Arbeleg
