Actually it should be but i rather would not use L2TP. Instead Sophos Connect and/or SSLVPN.

L2TP is some sort of old standard, which is not quite frequently used anymore.

Noob here....

Um im really noob but 10Mbps doesnt sound all that fast for a fibre link?
What are they trying to do that is slow, im wondering if your expectations are unrealistic?

Have you checked the firewall stats to see if the WAN link is getting maxed out?

Windows VPN will by default route all traffic through the VPN, you have to manually untick the box for "Use default gateway on remote network" in the advanced settings of the TCP/IP Properties of the adapter. Otherwise if they are using netflix or anything it will come down via your office through the VPN.
Assuming doing so meets with you organisations policies, although with a link that big im not sure you have many options.

On the off chance this the problem, Im just playing with sophos connect myself, looks like if this is the issue you cant configure it directly via the admin page or in windows.

I have an XG115 and no problems with nearly 10 users connected, although i note that the default IPSec settigns for L2TP appear to be um very weak.

PS. Did i say im a networking noob!
