An interesting query. Currently the GnatBOX filters by IP address. A feature request.
Could it be possible for the GnatBOX to have the ability to also take into consideration the MAC address? For instance, in filtering a TCP/IP packet, where I'm not interested in the IP address, but want to stop all data traffic on TCP port 25 from originating from MAC address 00AC45A321. Why? It's easy on a workstation to alter the IP address. For a MAC address (most NICs) the network adapter usually had to be changed. Does this make any sense?
