We have a customer that was forced to move away from a previous internet solution due to the demise of SDSL.
The SDSL was replaced with a 10MB EFM service. In addition to this, we replaced the old Cisco ASA 5510 which provided VPN connectivity through the Cisco VPN client, with a Sophos UTM 220.
The Sophos UTM provides a number of attractive security enhancements, however the SSL VPN is atrociously slow and sometimes indicates that there has been a disconnection from the server (when opening a file). Also, be aware that some of these file are tiny in size (50-300KB)
As a result of this we have a very frustrated customer. Sophos technical support say, 'it should just work'. We have worked with a 3rd party company contracted by Sophos who have indicated that this is a Windows issue.
In addition to the Sophos UTM, we have tried a Sonicwall NSA 250. This is also slow, but does not disconnect when opening files or browsing the directory srtucture through mapped drives.
A Meraki MX 80 was tried using VPN. This was slightly better, but nothing to write home about.
Windows PPTP was tried. This was slightly better again, but not our chosen method of VPN connectivity.
Can anyone put and end to our misery?
