I agree - Cisco needs to get some bugs fixed on this device. I just installed 3 of these for a small business customer and am starting to wish that I had not recommended this unit. I am having the same problem that you mention and more - SNMP traffic will not pass over the VPN tunnels, the devices periodically lock up, menu options stop working, the wireless connection drops periodically, the unit runs very hot... and so on. I am disappointed Cisco.
