Nighthawk AC2400 Smart WiFi Router Model AC2400
• Disable SIP ALG. Some voice and video communication applications do not
work well with the SIP ALG. Disabling the SIP ALG might help your voice and
video applications to create and accept a call through the router.
• Disable IGMP Proxying. IGMP proxying allows a computer on the local area
network (LAN) to receive the multicast traffic it is interested in from the Internet.
If you do not need this feature, you can select this check box to disable it.
• VPN Passthrough. VPN connects two secure networks over the Internet. The
router supports VPN passthrough for IPSec, PPTP, and L2TP.
5. Click the Apply button.

Set Up a Default DMZ Server
The default DMZ server feature is helpful when you are using some online games and
videoconferencing applications that are incompatible with Network Address Translation
(NAT). The router is programmed to recognize some of these applications and to work
correctly with them, but other applications might not function well. In some cases, one
local computer can run the application correctly if the IP address for that computer is
entered as the default DMZ server.
Warning:
DMZ servers pose a security risk. A computer designated as the default DMZ
server loses much of the protection of the firewall and is exposed to exploits from the
Internet. If compromised, the DMZ server computer can be used to attack other
computers on your network.
The router usually detects and discards incoming traffic from the Internet that is not a
response to one of your local computers or a service that you configured on the Port
Forwarding/Port Triggering page. Instead of discarding this traffic, you can specify that
the router forwards the traffic to one computer on your network. This computer is called
the default DMZ server.
To set up a default DMZ server:
1. Launch a web browser from a computer or mobile device that is connected to the
router network.
2. Enter http://www.routerlogin.net.
A login window opens.
3. Enter the router admin user name and password.
