Firewall WAN Zoning configuration best pratice

[GWong4]

Hi, If the customer environment have 3 different internet service provider. Should I got 3 different zoning or just configure 1 Zone for 3 different internet service provider.

This is purely based on your organisation's requirement. But if you want more granular control you can configure as three different zones.

Hi...based on your experience and the best practices. Which configuration is preferable?

For me, I would just do one untrust zone for all three.
