Loosing Network Connection on Mac since Endpoint Version 10.0.3

JanBelz
  • Feature: Network connection
  • Severity: high.
  • Summary: Mac looses network connection temporary

  • Observed behavior: 

    All Mac Clients in the BigSure EAP reporting network issues since version 10.0.3 turned up. Either connected via Wifi or LAN Cable they are loosing Network sporadically. I found out that complete uninstall of Sophos Endpoint fixes this error. For example my Mac is connected to the company by a Sophos UTM SSL VPN. When calling a internal webinterface via Browser the VPN connection gets killed immediately. If you need more Information just ask. I also have generated a SDU Report on my Mac.
  • Reproduce it: calling an internal http webinterface inside our network
  • Frequency: Every time
  • Environment: macbook pro connected by wire to a LAN or Wifi behind a sophos UTM
  • Other: Nothing more
  • Supporting logs, tool output etc: there is an SDU archive and the output from systemextensionsctl is attached

    Jan, the issue you have reported here was reported by a number of other people as the latest iteration of Sophos for BigSur is clashing with various VPN's. I have the same thing on Zscaler and you can see other discussions on Cisco and so on. I was checking the discussion to see if there is any update on my issues and stumbled across your post and decided to post this response.

    Dear Nicholas,

    thanks for your reply and confirmation of the issue.

    For me it seems, its not just interrupting the VPN. Today i am in the office and connected via LAN cable to the company LAN without VPN Client. If i call an internal webinterface thats routed to a different subnet inside the company by a Sophos UTM I loose my network connection for a short time.

    I also contacted sophos support, but as this is an EAP they told me to write about my issue in this community.
