I am deploying Imperva SecureSphere WAF in GCP. Currently it supports two NIC as per documentation but we are looking for complete segregation of traffic in, out and mgmt.
Could you please let me know whether Imperva SecureSphere supports three NICs?
If it supports only dual NIC, which configuration is best? One NIC for mgmt separate and another for IN/OUT or one NIC for mgmt/IN and another for OUT(external).
