repeating short time 'disconnecting'

Hoi and welcome to the UTM Community!

Show us a picture of the left side of the 'Advanced' tab in 'SSL VPN'.  Also, copy here about 30 lines from the SSL VPN log file and 30 lines after including 13:34:53.

Hi Bob, 

Thanks for the warm welcome and helping out! I'm not sure where i can find the advanced tab... I have uploaded a screenshot what i do have (in dutch). (RMB sophos SSL client icon / settings / ... ) Is this what you were looking for or should i look somewehere else?

Here's a part of the log from just now... (changed the original names for now to 'COMPANY')

EDITED for safety (log is available)

Hope there something in the Log that could help :)

Kind regards, Homer

Please show the corresponding information from the UTM's log and configuration.  If you're not the admin of the UTM, you might request that information from the admin.

Thank you very much in advance!

Hallo Mitsch and welcome to the UTM Community!

Please include the logs from 11:08:22 to 11:08:42.  Also, obfuscate IPs like 93.XX.YY.98, 10.X.Y.100, 192.168.X.200 and 172.2X.Y.51.  That lets us see immediately which IPs are local and which are identical or just in the same subnet.

Show us a picture of the left side of the 'Advanced' tab in 'SSL VPN' in WebAdmin.
