Issues since enabling authentication

kieran90

Several months ago I enabled Authentication on my XG v16 VM since this I've upgraded to V17 and still experience the below issues.

 

After enabling authentication at times I will randomly loose internet access this seems to happen in particular when waking a Windows 10 laptop from sleep although not exclusively. I have several firewall rules one with Authentication enabled and another just below with Authentication disabled. When this issue occurs if I try to ping an external address this times out however I am able to ping XG and various other Internal IP addresses although remote addresses over my IPSEC VPN are also unreachable.

 

When checking in the logs I'm unable to find any obvious issues and a reboot of the device in question seems to resolve the issue until the issue next occurs. I have STAS and RADIUS SSO enabled and both seem to be working fine except this issue.

 

Has anybody had any experience of a similar issue?

 

Any help is greatly appreciated

Thanks

    I had similar issue. In my case disabling logoff detection at STAS client and using only the firewall options to control the login time and transfer threshould did the trick...

    very interesting!  I have been battling this for quite some time.  over the course of a day, our network monitoring system will randomly notify me that our remote sites are down and various users (including my manager) will tell me the internet is bouncing. 

     

    I run constant pings to google and other sites and I see one random ping packet dropped, maybe 1 out of 40.  This is so random that it makes it difficult to troubleshoot. 

    I've tried disabling web filtering, IPS, etc.  I would never have guessed STAS/Authentication would have affected dropped traffic.

     

    Logoff detection has been disabled and I'll be monitoring to see if this is effective.

     

    Sounds like a bug to me, but Sophos and I frequently disagree on what constitutes a bug.
