Routers
MVG and UVG400 models have built-in SerVision routers. Each of these routers manages a small local network
(LAN) that can include up to four devices – the Video Gateway itself and up to three other devices. For example,
you could connect a PC and an IP-based cash box to the router, and they would all be part of the unit’s local
network.
The SerVision router makes it possible to connect MVG and UVG400 units to multiple networks – cable-based,
cellular, and WiFi – at one time.
Because the router is part of both the internal LAN and one or more external networks, it has two types of IP
addresses:

Local IP: An IP address on the internal LAN. This IP address identifies the router within the network that it
manages. It is static (fixed) and is
172.20.233.1
.

External IP: An IP on each external network to which it is connected (cabled LAN, WiFi, and/or cellular).
These IPs function as the public IP addresses of the Video Gateway units themselves, and are assigned by the
system administrators of the relevant networks.
The router contains a DHCP server that can automatically assign IP addresses to devices that are plugged into its
Ethernet ports. If you will not need to access a connected device remotely, you can configure the device to acquire
its IP from this DHCP server. In this case, the device will be able to connect to the external network, but remote
devices will not be able to access it. If you want to access the device remotely, you should manually configure its IP
address and other network settings as described below (for information about how to configure the network settings
of the device, consult the device’s documentation), and set up port forwarding for the device as described under
Port Forwarding , page 55.
NOTE:
The Video Gateway component of the Video Gateway automatically connects to the router component
when the unit starts up. The router's DHCP server assigns an IP address to the Video Gateway
component and port forwarding is automatically configured.
Setting Value
IP Address Assign a static IP address to the device. The IP must be in the range
