For several years, CSAs have been predominantly installed with a single network card.
The decision to install two network cards is made for two main reasons:
- If no DMZ is available.
- To conceal the administration console from external access.
In our specific scenario, the eth1 card cannot access the GSB console. Therefore:
- Eth0 is designated as the card accessible from the core server.
- Eth1 is designated as the card accessible from the internet.
