The default setup is 1500 bytes. Please note MTU modification may result in network

network service. System may pop up dialog box for you to confirm setup when you want to
change MTU setup. Click OK button to confirm current reboot, or you can click Cancel button
to terminate current modification. Before the modification, you can check the MTU of the
gateway; the MTU of the DVR shall be the same as or is lower than the MTU of the gateway .
