I'm at my wits end. My problem:- I have 2 customer - both with High Speed business class cable. One is Comcast Business Class with 100mb dn/ 10mb up, and one it Time Warner Business Class with 35mb dn/ 5mb up. Both have ASG120 installed running UTM9 and both have the exact same problem - bandwidth averages 5mb dn/ 3mb up.
Here is my setup. No IPS, No Web filtering - Straight no fuss internet. If you plug a machine directly into the modem, you get the prescribed speeds. I plugged in a Cisco SA520 - correct speeds. Plugged in a cheap Cradlepoint router - correct speeds. I even messed with the hardware to see if there was an issue with port speeds and duplexing.
I called sophos support - all the guy could say is "looks like their modem does not like our firewall" - Seriously?
Any suggestions on how to fix this will be greatly appreciated.
