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 ?

  • Sorry for the delay in response, but I have had a discussion with Sophos Support about this and they dont seem to have a fix for this. Not sure if you maybe got it sorted but we still have this issue

  • Jeff, My customer with an XG210 and a Gig internet connection can't download from file server (remotely) over VPN any faster that 2-3Mbps, so how for the love of cheeze-whiz are you getting 25-35?  That's something that Sophos support was never able to help me resolve. smh.

  • Everything off I can turn off for VPN traffic, the VPN firewall rule near the top (just under my phone rules). 

    Also, a recent game changer as been switching from IPSec to SSL. My speeds jumped up 10-fold. There's a couple people with cruddy service at their homes, so they're out of luck. Most most users are now have speeds in the 100s (I have GB at home and I'm anywhere from 350-450mbps).

    At first users to annoyed at changing how they connected (again) since we had just switched from as UTM a few months ago. The annoyance stopped when they saw how fast they were transferring files.

    Thanks,

    Jeff
