I am convinced of the replacement method of the failure machine of firewall equipment.

First, fault background

A customer is convinced that a load balancing equipment failure has been sent back to the original factory for maintenance. Now a standby machine is required for cold backup, which requires the same configuration as the mainframe. When the mainframe fails, it can be put into use directly.

Second, the way to deal with it

1. Get a backup machine from the deep conviction site, as there is no AD device at the site, replace it with AF to confirm that the device can be used normally.

two。 Configure with reference to the configuration of the main equipment at the customer site

3. Replace faulty equipment

III. Configuration process

According to the AD equipment being used at the customer site, the standby is configured in the following four aspects:

1. Configure Port

According to the network architecture, configure the firewall port, telecom port, connection port and LAN port.

two。 Configure routin

Configure static routes, default routes can be configured as needed

3. Configure source address translation

4. Configure destination address translation

IV. Processing results

Go to the customer site to replace the faulty equipment with the standby machine

Problem solved!
