How to set up Protocol Binding on the Linksys Gigabit VPN Router, LRT224

Some special network service cannot support multi-WAN such as on-line gaming.  You can make the outbound traffic to a specified destination leave the router from a specified WAN port through Protocol Binding or Static Routing.

Protocol Binding is used to define specific IP addresses or specific application service ports to go through a user-assigned WAN for external connections.  For any other unassigned IP addresses and services, WAN load balancing will still be carried out.

The instructions below will guide you on how to configure Protocol Binding on your Linksys Gigabit VPN Router, LRT224.  If you prefer to configure Static Routing on your router, click here.

NOTE:  In the load balance mode of Assigned Routing, the first WAN (WAN1) cannot be assigned.  It is to be saved for the IP addresses and the application Service Ports that are not assigned to WAN2 for external connections.  In other words, the first WAN (WAN1) cannot be configured with the Protocol Binding rule.  This is to avoid a condition where all WANs are assigned to specific Intranet IP or Service Ports and destination IP, no more WAN ports will be available for other IP addresses and Service Ports.
 
Step 1:
Access the router's web-based setup page.  To learn how, click here.

Step 2:
Click the Configuration tab on the header.


Step 3:
Click System Management > Dual WAN in the navigation tree on the left side.


Step 4:
Under PROTOCOL BINDING, enter the correct values according to the network information of your network devices:


 
  • Service
Select the Binding Service Port to be activated.  The default ports like ALL-TCP&UDP 1~65535, WWW 80~80, FTP 21 to 21, and many more can be selected from the drop-down option list.  

NOTE:  If the service you want to use is not on the list, you can add one from Service Management button.
  • Source IP
This is where one can assign packets of specific Intranet virtual IP to go through a specific WAN port for external connection.  Enter the Intranet virtual IP address range.  (Example:  When “192.168.1.100~192.168.1.150” is used, the binding range will be 100~150.)
 
NOTE:  If only specific Service Ports need to be designated, while specific IP designation is not necessary, enter “0” in the IP boxes.
  • Destination IP
Enter the External Static IP Address.  (Example:  If connections to destination IP address 210.11.1.1 are to be restricted to WAN1, the External Static IP Address 210.1.1.1 ~ 210.1.1.1 should be used.)

QUICK TIP:  If a range of destinations is to be assigned, enter a range such as 210.11.1.1 ~ 210.11.255.254.  This means the Class B Network Segment of 210.11.x.x will be restricted to a specific WAN.

NOTE:  If only specific Service Ports need to be designated, while a specific IP destination assignment is not required, enter 0 into the IP boxes.
  • Interface
Select the WAN port for which users want to set up the binding rule.
  • Enable
Tick this box to activate the rule.

Step 5:
Click Add to list.
    
NOTE:  The priority for rule execution depends on the rule order in the list.  A rule located at the top will be executed prior to those located below it.  Users can arrange the order according to their priorities using the Move Up and Move Down buttons.  

Step 6:
Click  at the bottom of the page to finish the configuration.
