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.

    I was fairly certain that you were suffering from the "classic" problem in your situation - Anti-UDP Flooding, and that also is recorded in the Intrusion Prevention log.

    Cheers - Bob
