You must first enable the firewall from the Security page for pass-through rules to be applied. Refer to Configuring Basic WAN Firewall Settings.
Adding a Pass-Through Rule
This section outlines how to add a pass-through rule.
To add a Pass-Through Rule
Choose Network > Pass-Through Rules.
Configure settings using the information in the following table as a guide.
Field | Description |
---|
Protocol | Choose ports and protocols that are allowed through the system. • Custom-UDP—Allows the specified UDP port to pass through the system • Custom-TCP—Allows the specified TCP port to pass through the system • Any—Allows all ports and protocols through the system. Ports are not required because not all protocols support the concept of ports. For the remaining protocol options, the correct protocol and port is automatically applied for the selected addresses. |
Input Interface | Choose the interface where data is received that is destined for the forwarded subnet destination address: • WAN • LAN • VoIP • VLAN_1 |
Source IP | Enter the source address or network to be forwarded through the firewall from the Input Interface to the Output Interface. When left blank or set to 0.0.0.0, all addresses in the subnet are selected. |
Source Mask | Enter the network mask that applies to the Source IP to create the host or range of IP addresses that are forwarded through the firewall. When left blank or set to 0.0.0.0, all destination addresses are allowed for this rule. |
Custom Source Ports | Enter the source port number that is allowed through the system when either Custom-UDP or Custom-TCP protocol is selected. The Custom Port parameter is not required when Any or a protocol other than Custom-UDP or Custom-TCP is selected. Note: For multi-DLCI single T1 Frame Relay links: When VOICE_LAN or VOICE_WAN are selected using the Any rule, traffic is automatically forwarded from VOICE_LAN to VOICE_WAN. Traffic from VOICE_WAN to VOICE_LAN is dropped unless a rule allows it through. |
Output Interface | Choose the interface where data is received and then sent from the forwarded subnet destination address: • WAN • LAN • VoIP • VLAN_1 |
Destination IP | Enter the destination address or network to be forwarded through the firewall from the Input Interface to the Output Interface. When left blank or set to 0.0.0.0, all addresses in the subnet are selected. |
Destination Mask | Enter the network mask that applies to the Destination IP to create the host or range of IP addresses that are forwarded through the firewall. When left blank or set to 0.0.0.0, all destination addresses are allowed for this rule. |
Custom Destination Ports | Enter the destination port number that is allowed through the system when either Custom-UDP or Custom-TCP protocol is selected. The Custom Port parameter is not required when Any or a protocol other than Custom-UDP or Custom-TCP is selected. |
Target | Choose the action that is applied to packets that match the rule. The options are ACCEPT or DROP. |
