In Router mode, routing functionality is enabled in the gateway, the DHCP server runs and all
the LAN and Wi-Fi clients can obtain private, LAN IP addresses via DHCP. The NAT
functionality in the gateway translates the private IP to the eRouter IP for external Internet
access. When the gateway is provisioned with dualstack, then DHCP v6 and v4 servers would
run in the gateway for the LAN clients.
In Bridge mode, the routing functionality is disabled (DHCP and NAT functionalities are similarly
disabled). All LAN clients receive public IPs from the MSO. The Wi-Fi network is disabled in
Bridge mode.
Router Mode:
If in Bridge mode and Router Mode is selected, the Gateway will reboot automatically and
operate in Router Mode after reboot. Routing functionality is enabled with Wi-Fi and LAN set to
active. The management IP address will change LAN configuration (such as from x.x.x.x to
y.y.y.y. For instance, it may change from 10.0.0.1 to 192.168.0.1.)
Figure 6.4
Bridge Mode:

MTU, etc.) needs to be obtained from the MSO and entered through the WebUI.
