Cisco VPN beeing throttled?

x1xxomx1xx
Hi all

i have a Sophos UTM Home Edition on a vSphere ESX Host connected to FTTH on the WAN side and Cisco SG300 switches on the LAN side. I have a Cisco 881 router connected to the lan over one of the SG300 switches, it is making a connection to an office vpn. I only get 2Mbps Down and 2Mbps Upload - if the router is placed behind the Sophos UTM. Directly connected to the WAN I can get approx 35/10. 

Any advice on how to optimize this performance issue? It seems as if some kind of bandwith throttling occurs but nothing is activated on the sophos from my end.

    hi Bob

    no indication at all...i also turned off IPSEC Tunnels, ATP, Int.Prev., changed the MTU to 1350 on WAN,... nothing helps. 

    The Speedtest spikes to 7Mbps and then immediatly goes to 2Mbit download, upload pretty much stays at 2Mbit. 

    I do have a Windows DC that sends ICMP to the UTM which pop up in the Firewall logs but thats it. 

    My FTTH Link is 1Gbits/1Gbits. 

    regards
