Before enabling an L2VPN (Layer 2 VPN) in NSX, a Route-based IPSec VPN must be configured. Route-based VPNs create a secure tunnel over which Layer 2 traffic can be extended, allowing for the creation of L2VPN connections. This setup is required to establish the underlying secure connectivity that L2VPN relies on for traffic between sites.

If Distributed Firewall Rule hit counts are not being logged, it is likely because Distributed Firewall Rule logging is not enabled. For hit counts to appear in the logs, logging must be explicitly enabled on each firewall rule where tracking is required. Without enabling logging at the rule level, no hit count information will be recorded in syslog.
