Expand All
  1. Sign in to the Admin WebGUI then click
    Firewall.
    You must be connected to the network to access the admin page.
  2. Click
    Static NAT.
  3. Configure the following then click
    Save
     for the changes to take effect:
    • Status
       : The state of each Static NAT entry (usually Enabled).
    • Public IP Address
       : A public IP address, assigned by your service provider. This should not be the WAN IP address of the Gateway.
      Assigning an arbitrary public IP address will not work.
    • Local Host
       : IP address of the LAN-side host.
    • Bypass Firewall
       : When enabled, unsolicited traffic bypasses any firewall rules.
    • Allow Inbound
       : When enabled, the Gateway forwards unsolicited traffic destined for the public IP address to the local host.

    .
    You must be connected to the network to access the admin page.
  2. Click
    UPnP
    .
  3. Configure the following then click
    Save
     for the changes to take effect:
    • UPnP
       : Choose Enable to enable UPnP.
    • Advertisement Period
       : The period, in seconds, the Gateway broadcasts UPnP information. A shorter advertisement period ensures control points have current device status, at the expense of additional network traffic.
    • Advertisement Time to Live (TTL)
       : The number of hops before the advertisement disappears. (A hop is the number of steps allowed to propagate for each UPnP advertisement.)
    • IGD/NAT-T
       : Internet Gateway Device Protocol for Network Address Translation (NAT). Must always be enabled.
