Protocol Internal port External port Interface IP address It displays the network protocol used by the gateway. It displays the internal ports opened by UPnP (if any). It displays the external ports opened by UPnP (if any). It refers to the LAN/VLAN segment on which the UPnP option is enabled. It displays the IP address of the UPnP device detected by the gateway. Firewall Policy The Firewall section of the Security deals with the various methods adopted by router to ensure a safe and secure network. In this section, you will learn about the Firewall rules configuration on the IPv4 networks. These are the rules defined to keep a check on the incoming and outgoing traffic of the network. You can state which traffic is to be allowed or blocked. Similarly, the Port Forwarding method can restrict access to traffic entering your network while allowing only specific outside users to access specific local resources. When you have multiple public IP addresses and multiple servers across the firewall, the 1:1 NAT method is used. This section covers the following topics: IPv4 Firewall Rules Port Forwarding Port Triggering IP Rule Outbound (LAN/DMZ to WAN) rules restrict access to traffic leaving your network, selectively allowing only specific local users to access specific outside resources. The default outbound rule allows access from the secure zone (LAN) to either the public DMZ or insecure WAN. On the other hand, the default outbound rule is to deny access from DMZ to insecure WAN. In addition, you can restrict VLAN to VLAN or LAN to VLAN traffic using IPv4 Firewall rules. The fields displayed in the IPv4 Firewall Rules table are as follows: Field Priority Name Source Interface Destination interface Service Source Destination Schedule Description It specifies the priority of the configured rule. It specifies the name of the firewall rule It specifies the source interface It specifies the destination interface It displays the service for which the firewall rule is defined. It displays the source IP address range, a specific IP address, or Any for all IP addresses on which the firewall rule is applied. It displays the destination IP address range, a specific IP address, or Any for all IP addresses on which the firewall rule is applied. It displays the schedule when the firewall rule is applied.

IP Rule
Outbound (LAN/DMZ to WAN) rules restrict access to traffic leaving your network, selectively allowing only specific local users to access specific
outside resources. The default outbound rule allows access from the secure zone (LAN) to either the public DMZ or insecure WAN. On the other
hand, the default outbound rule is to deny access from DMZ to insecure WAN. In addition, you can restrict VLAN to VLAN or LAN to VLAN traffic
using IPv4 Firewall rules.
The fields displayed in the
table are as follows:

Source
It displays the source IP address range, a specific IP address, or Any for all IP addresses on
which the firewall rule is applied.
