Hi,

Yes,  F5 allows it. If the backend server expects the same certificate or trusts only a specific certificate (mutual trust), using the same one might make sense.

The main advantage it is simple trust model - If the backend server does SSL verification and only trusts specific certs, using the same cert can make things easy. Also If mutual TLS is required, the same certificate (or CA chain) may help streamline it.

 

The main disadvantage is - It’s generally not best practice to reuse the same cert between public-facing and internal services. Separation reduces attack surface. 

 

Always using different certificate is best practice
