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.

Setup for VLAN tagging (IEEE 802.1Q)
To setup the V-Tap to take part of a Virtual LAN, the network cable
must be connected to the LAN port, that is marked '4' on the box.
Also, the following option must be added to the IP Address:
/VLAN<0-4095> : Set the VID field and enable VLAN tagging.
/PRIO<0-7>
The IP Address is then for example: 192.168.0.12 /VLAN256 /PRIO1
All web access and the Tunnel connection on that LAN port are then
sent with VLAN tags inserted, and the system only answers to packets
with the same VID inside their tags.
The other LAN port can still be used to access the V-Tap without tags.
Network traffic between the two LAN ports directly will pass unchanged
packets between each other, with or without VLAN tags.
