Sophos Connect - slow and freezing connections for SMB and RDP

I'm using Sophos XG 4500 v19 and we have noticed that connections to SMB servers when using Sophos connect remote access with default IPSEC profile are slow and unresponsive.

DoS protection is off  and we are not using traffic shaping.

Any Ideas ?

  • Did you run your firewall with older firmware before and was performance OK there?

    Is this for all users or only some?

    We've once had SMB (no RDP) performance issues over VPN caused by software based file encryption on the SMB file server. This was not noticable in LAN, only VPN.

  • RDP via Sophos Connect VPN client seems to be OK on Windows but is disconnecting on Mac OS. SMB is slow both in Windows and Mac OS. I can't confirm if this was ok on the old firmware.
