Configuring Transmission Transmission
external ports, the router can forward them to the corresponding host. Port Triggering is
mainly applied to online games, VoIPs, video players and so on.
 NAT-DMZ
When a PC is set to be a DMZ (Demilitarized Zone) host in the local network, it is totally
exposed to the internet, which can realize the unlimited bidirectional communication
between internal hosts and external hosts. The DMZ host becomes a virtual server with
all ports opened. When you are not clear about which ports to open in some special
applications, such as IP camera and database software, you can set the PC to be a DMZ
host.
 ALG
Some special protocols such as FTP, H.323, SIP, IPSec and PPTP will work properly only
when ALG (Application Layer Gateway) service is enabled.
Bandwidth Control
You can control the bandwidth by configuring bandwidth control rules for limiting various
data flows. In this way, the network bandwidth can be reasonably distributed and utilized.
Session Limit
The amount of TCP and UDP sessions supported by the router is finite. If some local hosts
transmit too many TCP and UDP sessions to the public network, the communication quality
of the other local hosts will be affected, thus it is necessary to limit the sessions of those
hosts.
Load Balancing
You can configure the traffic sharing mode of the WAN ports to optimize the resource
utilization.
Routing
You can configure policy routing rules and static routing.
Policy routing provides a more accurate way to control the routing based on the policy
defined by the network administrator.
Static routing is a form of routing that is configured manually by adding non-aging entries
into a routing table. The manually-configured routing information guides the router in
forwarding data packets to the specific destination.
