N750 Wireless Dual Band Gigabit ADSL Modem Router DGND4000
Device Mode
When the wireless modem router is in Router mode, this screen allows switching to Modem
mode, where the wireless modem router acts as a pure bridge or DSL modem.
Routing, firewall, wireless support, USB, and the t
r
affic meter are not available in Modem
mode. A typical application is a small-to-medium business scenario where the wireless
modem router is used for DSL connectivity behind a carrier class router or firewall or security
device manager. When the wireless modem router is in Modem mode, this screen allows
switching back to Router mode with all of the standard features.
To switch the device mode:
1. Click ADVA
NCED > Advanced Setup > Device Mode to display the following screen:
2. From the Device Mode list, select Router (Modem + Router) or Modem (Modem only).
3. Click Appl
y to save your settings.
VPN Policies
Manage your VPN policies from the VPN Policies screen.
• Traffic covered by a policy is automatically sent through a VPN tunnel.
• Where traffic is covered by two or more policies, the first matching policy is used. In this
situ
ation, the order of the policies is important. However, if you only have one policy for
each remote VPN endpoint, then the policy order is not important.
• T
he VPN tunnel is created according to the parameters in the SA (security association).
• The remote VPN endpoint must have a matching SA, or else
it refuses the connection.
