I am currently doing a replication from my barracuda appliance (backups) to the cloud (barracuda.com). The techs at Barracuda say that my transfer rate is 297Kb.My upload speeds slow down to more than half of what I should be getting from my ISP and I also have a high ping rate to my isp about 340ms . My barracuda appliance is behind my firewall. I have tested for packet drops on the firewall using the ip of my appliance. There are 0 packet drops. Also when I ping to hosts on my network including the barracuda appliance the ping rate is less than 1 ms.
However, when I remove the appliance from the lan. The upload speed goes back up to what it should be and the ping rate to my isp goes down to about 8ms.
Any ideas as to what would be causing the slow transfer rate?
