UPnP

Allow Internet access to be disabled	If checked, then UPnP users can disable Internet access via this device. If Disabled, UPnP users can NOT disable Internet access via this device.

MTU
MTU	MTU (Maximum Transmission Unit) value should only be changed if advised to do so by Technical Support. Enter a value between 1 and 1500. This device will still auto-negotiate with the remote server, to set the MTU size. The smaller of the 2 values (auto-negotiated, or entered here) will be used. For direct connections (not PPPoE or PPTP), the MTU used is always 1500.
