5. Configure the firewall
Enable the firewall.
Create a firewall policy.
Set the firewall session timeouts for TCP, UDP and other packet types, in minutes.
Add the public and private interfaces to the firewall policy.
Add the redundancy management VLAN to the firewall policy as a private interface.
You do not need to add firewall access rules at this step. This example uses triggered scripts
to dynamically add access rules, depending on which load balancer is the master (see step 9).
6. Disable the GUI and the HTTP server on port 80
You cannot use the router's GUI or its HTTP server on port 80 when load balancing web
traffic. Therefore, you need to either disable the GUI and server, by using the following
commands:
or change the port that the server uses. For example, to change the port to 8080, use the
following command:
You can then use the GUI by pointing your browser to the router's private address and the
new port (in this example, 192.168.1.200:8080).
Note that this configuration uses some advanced settings that are not available through the
GUI, so you cannot use the GUI to create this configuration. You also cannot use the firewall
pages in the GUI to modify this configuration's firewall settings, because the GUI does not
recognise this firewall policy. However, you can use the GUI to monitor the router.
