server
If the interface for accessing the Internet (e.g. WAN port) is config-
ured statically then you must configure at least one accessible
DNS server for resolving DNS names (e.g Google’s name server
with IP 8.8.8.8).
If the Interface for Internet access is set to DHCP then typically
the DNS server will be retrieved from DHCP server. In this case
you do not need to enter the IP address of a DNS server.
Generally at least one DNS server must be configured for resolv-
ing hostnames to IP addresses. A DNS server is mandatory if the
Router is configured for using the u-link Remote Access Service.
Note: See Tab „State“ to check the currently configured name
server(s).
Register host name at
DHCP server
If enabled all DHCP requests by the device will register the speci-
fied hostname at the DHCP server. If the DHCP server is running
dynamic DNS updates according to RFC2136 this will result in a
valid DNS record on the DNS server with the specified Hostname
Use all servers concur-
rently
If set active, incoming queries will be forwarded to all configured
DNS servers. The fastest reply will be sent back to the requester.
Otherwise, only one DHCP server will be used.
Enable DNS proxy
Device acts as DNS server and will forward DNS requests to the
configured DNS servers. Please ensure that the DNS proxy is
only running on the required (internal) interfaces.
