I. brief introduction:

1. Connection method: public network-> firewall-- > switch

2. Server migration and switching of all ip addresses

2. Ip changes configured in the firewall:

Example: the old address is 0.0.8.34, and the new address is 0.0.0.82

PS:

The firewall can use multiple addresses to surf the Internet, as long as the access network cable provides the function that both the new and old ip addresses can access the Internet, so you can ensure that the new address can be used properly before deleting the old configuration.

1. Change the access address:

A) add a new access address:

i. Connect the corresponding network port with a network cable (the usual network cable is OK, and some older firewalls may need to use cross lines). This is the first network port (eth0). If your firewall is still the factory default access address of 192.168.1.254, the network port you should connect to is the MGMT interface.

ii. Configure the local ip to be the same ip segment, and neither the gateway nor the dns needs to be entered.

iii. Enter the old address, enter the login page, enter the account password, and enter the background.

iv. Add a new access address to the original

Note: when creating a new route, the destination address is 0.0.0.0 so that you can remotely connect to the firewall with any ip and log in to the firewall background.
