Hello, I'm trying to prevent packet fragmentation for winbind => Samba DC traffic on UDP 750 (Kerberos) due to VPN encapsulation. I have TCP MSS adjustment set to prevent this for TCP but I'm trying to solve for this traffic too without modifying MTU which would affect other traffic. It isn't clear from the documentation the effect of max xmit. Thanks, Arthur This e-mail and any attachments may contain CONFIDENTIAL information, including PROTECTED HEALTH INFORMATION.

Also Samba doesn't use Kerberos 4, Kerberos 5 is on port 88.
