Hi
I've recently purchased an UTM 220 + 2x RED10's and setup them through the RED wizard. They connect & the clients get DHCP leases and everything seems fine. RED10's running in 'Standard/Unified mode" / DHCP Client uplink mode.
However I have a problem that clients behind the RED10's cannot resolve FQDN from the HQ-UTM220 network, such as the hostname of my DC, SQL Server, etc. However I can successful ping via ipv4.
Side note, when I use the client SSL VPN the remote clients can resolve the FQDN
Under Network & Services > DNS > Request Routing the MS based AD/DC Server is configured. Where AD/DC is 10.10.8.50.
My Main network is 10.10.8.0/22
Red #1 - 172.16.0.0/24 - interface 172.16.0.1
Red #2 - 172.16.0.1/24 - interface 172.16.1.1
DHCP Red #1
Start - End 172.160.0.100-150
DNS Server1: 172.16.0.1
DNS Server2: 0.0.0.0
DGW: 172.16.0.1
Corresponding for Red #1 but with the +1 IP.
Any idea what I should be checking for or missing out on?
My DNS Forwarder is my ISP's DNS address. Should I add my PDC/AD there as well?
Thanks
