    FYI. I ran into a terrible problem using a Fortigate VM00. 5.4.1 will not run because the virtual appliance only has 1GB of memory available. Fortinet was nice enough to diagnose the problem, but really does not have an easy way of upgrading to the 2GB virtual appliance.

    Problems of download speed, I have a fortigate 30e and I have problems in the download speed 4.2 mbps, instead in upload speed is correct 89.55 mbps, I do not know where the problem may come from. I have version 5.4.1 build1064. You can help me.
