 // When this is defined, a check will occur inside the IPv4 and IPv6 filters. For IPv6 packets, if no IPv6 source/destination IP addresses are set, but there is an IPv4 address, it will ignore the filter. The same goes for IPv4, if there is no IPv4 source/destination IP addresses set, if an IPv6 address is set, it will ignore the filter.

 // If uncommented, rate limits for clients are determined using the source IP, port, and protocol instead of just the source IP.
 // This allows for more precise rate limits (connection-specific instead of a single source IP).
