We're having serious issues with SightMax on demand locking up. Our firewall log (Linksys BEF-SX41) shows packets transmitting fine, but then dropping packets when the SightMax server tries to connect to our "higher level" ports (or any port other than Port 80). It's our understanding Sightmax "On Demand" is supposed to only communicate via Port 80; however, the firewall logs show something different happening. Has anyone find a workaround, or a fix? We're using ver. 2.5 Build 5.0.
