V-Tap ISDN BRI Manual EN v2.6 Dec 2018 © 2017-2018 Vidicode 13

Gateway Address

The Gateway address is used by the V-Tap unit when access outside
the local network (LAN) is required. This sort of access can be needed
by the Tunnel protocol for streaming to a remote computer and/or
by the NTP feature for obtaining the current date and time.
In case DHCP is used, the gateway address is automatically obtained.

DNS Server Address

The Domain Name Service (DNS) is needed in case a name is entered
instead of an IP address for the Tunnel server and/or the NTP server.
The default DNS address 8.8.8.8 is the Google Public DNS, but the
Gateway must be defined also before this address is reachable.
In case DHCP is used, the DNS address is automatically obtained.
