ES configuration dual network card
Problem Description
The two departments of the client need to use the same ES platform for authorization, but the networks of departments A and B are not interconnected. Department A needs the address range to be 192.168.0.0/16, with the ES address being 192.168.1.120, while Department B's range is 172.16.0.0/16, with the ES address being 172.16.1.120.

ens33 connects to Department A network, ens34 connects to Department B network.
Configure server network card information:
Sorry, but "ens33" is not a word or phrase that can be translated. It appears to be a network interface name used in Linux operating systems.

Suggestions and Summary
Note: Adding a network card will cause the gateway ID to change. Adding a network card operation needs to be done before opening the serial number.
The IP ranges of the two department networks cannot conflict.
