The solution for this issue has been found... a bug introduced by a new forced configuration...:

Making this change solved it for me...

Just in case you need help with editing the file, here is some info on "vi", linux text editor..

Additional Notes:

I have create a 2012 R2 RRAS server and put that between the UTM and the ISP via a LAN/WAN NAT. When testing directly from the RRAS Server, I get the full 250M/25M (down/up), but from a device behind the UTM I get 250M/10-14M, again I expect some loss with the additional hops and translation.

So far:

Physical(Laptop) -> Modem -> Inet: 250M/25M
HyperV Guest(Windows) -> Modem -> Inet: 250M/25M
Client -> HyperV UTM -> HyperV Guest(Window NAT) -> Inet: 250M/10-14M
Client -> HyperV UTM -> Modem -> Inet: 250M/3-5M

I doubt anyone from Sophos would pick this up, but something is not right and I have no other blocking features on but FW... Maybe someone will come back with something.

Thanks...

I have validated that the issue lies within the SOPHOS UTM VM, but the question is what...?

Since my UTM is on a HyperV host, I thought that maybe it has to do with the vNic, vSwitch, duplexing or something. I have another guest on that host that I have attached to the vNic/vSwitch, and on that VM I get full upstream/downstream like I should. So there is something in the UTM that is preventing me from getting full upsteam... I dont know if it is a residual configuration that is hanging around or what... Any ideas of where to look would be awesome...

Down/Up
Physical laptop: 262.65M/29.35M
Guest VM(HyperV: Same Host/vswitch as UTM): 258.33M/29.97M
Sophos UTM(HyperV): 278.68M/3.75M

Thanks,
