Port Triggering is a way to dynamically forward ports to a LAN PC on demand. With this feature, Gateway remembers the IP address of the computer requesting data so that when the requested data returns back through gateway, it directs the data back to the computer by looking at its IP address and port mapping rules. The objective of this document is to setup port triggering on RV180 and RV180W routers
• RV180
• RV180W
Step 1. Access the device through web-based utility and then choose Firewall > Port Triggering. The Port Triggering page opens.
• Name — Name field displays user-defined name of the rule.
• Status — Status field displays the current status of the rule.
• Protocol — Protocol field displays whether the port uses TCP or UDP protocol.
• Outgoing Ports — Outgoing Ports field displays port number or range of port numbers that triggers this rule when a outgoing connection request is made. If the connection uses only one port, then both the Start Port and End Port fields display same values.
• Incoming Ports — Incoming Ports field displays port number or range of port numbers used by remote system that receives the request. If the incoming connection uses only one port, then both the Start Port and End Port fields display same values.
Step 7. To add a new rule, Click Add to open the Add/Edit Port Triggering page.
Step 1. Enter your Application name in the Name field.
Step 2. Check the Port Triggering Rule checkbox to enable the new rule.
Step 3. Choose protocol for the new rule from Protocol drop-down list.
Step 4. Triggered port range are the ports used by outgoing traffic. In the first field, enter the starting port number of the triggered range. In the second field, enter the ending port number of the triggered range.
Step 5. Response port range are the ports used by incoming traffic at gateway. In the first field, enter the starting port number of the response range. In the second field, enter the ending port number of the response range.
Step 6. click Save to save the settings.
Step 1. Check a rule in port triggering rule table to edit the fields.
Step 2. Click Edit to open the Add/Edit Port Triggering page to edit a selected rule.
Step 3. Edit the rule and then click Save to save the settings.
