    sudosysctlnet.inet.tcp.path_mtu_discovery=0 && sudosysctlnet.inet.tcp.tso=0

    This command will only temporarily enable T2E. Restarting the Mac will delete the connection.

    sudo bash –c ‘printf “#QNAP\nnet.inet.tcp.path_mtu_discovery=0\nnet.inet.tcp.tso=0\n#QNAP\n” >> /etc/sysctl.conf’

    This command will permanently apply these settings.
