I have two Sophos UTM Home endpoints, one at my house and another at my friends with a VPN between us. I cannot get speeds over 30Mbps on the VPN from me to my friends house but if he downloads directly from my web server he maxes my connection out at around 75Mbps.
My UTM - Dual Core Celeron 2.9Ghz 4GB
All security services enabled
75/75Mb fiber (tested to 80/80)
Friends UTM - Dual Core Celeron 2.9Ghz 4GB
All security services enabled
105/10Mb cable (Tested to 125/12)
VPN is AES128 SHA2 128 with PFS.(I have tried all different types of combinations) Both systems show about 5-9% CPU load when transferring, and I have even tried turning off the IPS/Web proxy with no difference in speed. Our previous configuration was with an EdgeRouter Lite on both ends which allowed IPsec VPN speeds to max my connection out.
The issue is on the UTMs somewhere but I cannot seem to find something that works.
