See Incontrol2 Firewall Rule - Region blocking - slow to load - #8 by soylentgreen for related info.
After getting the regional firewall rules working, unfortunately my poor old Balance One seems overwhelmed:
100% CPU usage at only 200mbps.
Is this expected behavior or a bug? I’m thinking of upgrading to a B One - would the B One be able to handle complex firewall rules w/o hitting 100% CPU?
