Action You have the following options:
• Add Add a firewall rule.
• Edit Make changes to a firewall rule. Click Save to save
your changes.
• Del Delete a firewall rule.
Static Routes
(Available in Advanced view.) You can manually add
static routing rules to the system routing table; you can
set a rule that a specific target IP address (or range of IP
addresses) passes through a specific gateway. Click the +
button to display the Static Routes section.
Enabled Enables the specific static route. All the added
static routes are saved in the system configuration file;
however, only the enabled static routes are active on the
device.
Target Network IP Specify the IP address of the
destination.
Netmask Specify the netmask of the destination.
Gateway IP Specify the IP address of the gateway.
Comment You can enter a brief description of the
purpose for the static route.
Action You have the following options:
• Add Add a static route.
• Edit Make changes to a static route. Click Save to save
your changes.
• Del Delete a static route.
Port Forwarding
Port forwarding allows specific ports of the hosts on the
local network to be forwarded to the external network
(WAN). This is useful for a number of applications (such
as FTP servers, VoIP, gaming) that require different host
systems to be seen using a single common IP address/
port. Click the + button to display the Port Forwarding
section.
Enabled Enables the specific port forwarding rule. All
the added port forwarding rules are saved in the system
configuration file; however, only the enabled port
forwarding rules are active on the device.
Private IP The IP address of the local host that needs to
be accessible from the external network.
Private Port The TCP or UDP port of the application
running on the local host. The specified port will be
accessible from the external network.
Type The Layer 3 protocol (IP) type that needs to be
forwarded from the local network.
Source IP/mask The IP address and netmask of the
source device.
Public IP/mask The public IP address and netmask of the
device that will accept and forward the connections from
the external network to the local host.
Public Port The TCP or UDP port of the device that will
accept and forward the connections from the external
network to the local host.
Comment Enter a brief description of the port
forwarding functionality, such as FTP server, web server, or
game server.
Action You have the following options:
• Add Add a port forwarding rule.
• Edit Make changes to a port forwarding rule. Click Save

• Del Delete a port forwarding rule.
Multicast Routing Settings
With a multicast design, applications can send one copy
of each packet and address it to a group of computers
that want to receive it. This technique addresses packets
to a group of receivers rather than to a single receiver. It
relies on the network to forward the packets to the hosts
that need to receive them. Common routers isolate all
the broadcast (thus multicast) traffic between the local
and external networks; however, the device can provide
multicast traffic pass-through functionality.
Multicast Routing Enables multicast packet pass-through
between local and external networks while the device is
operating in Router mode. Multicast intercommunication
is based on Internet Group Management Protocol (IGMP).
Multicast Upstream Specify the source of multicast
traffic.
Multicast Downstream Specify the destination(s) of
multicast traffic.
Add Add a destination.
Del Delete a destination.
