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 ?
For users reporting this, please share your Case ID, so this issue can be brought to GES with a higher priority.
In the meantime users that remain on v19 and using XGS hardware, can you check if…
We are running XGS3300 SFOS 18.5.2 MR-2-Build380We are having SMB speed issues between on-prem firewall and Sophos virtual firewall running in Azure. Case #05611513Sophos support offered no troubleshooting when I asked them if this could be MTU size related since we are having issues with anything larger than 1378 bytes over the tunnel. They replied with the following:Access the Sophos Firewall console via SSH. Select 5. Device Management > 3. Advanced Shell. Run the command: cish Run the command “ system ipsec-acceleration disable”I'm going to try this but it would be nice to know if we should do some troubleshooting first.
