We've noticed that the support for SMBv1 was disabled in MWG 126.96.36.199, the default is now the SMBv2 protocol. The problem is that we have an old windows 2003 domain and the communication with our 188.8.131.52 appliance is now broken.
Is there any way to re-enable SMBv1 protocol in MWG 184.108.40.206?
Thanks in advance.
no this is not possible. You would need to re-image to an older version in case you already have upgraded your MWG.
In security perspective, I would suggest to update windows 2003 domain to a version that starts supporting SMBv2.
Hope you are doing well.
MWG now only supports SMB v2. All others support smbv2 except windows server 2003.
