Backup DNS

DNS IP Address

Enter the IP Address of the DNS (Domain Name Server) here. These DNS will be used only if the primary DNS is unavailable.

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.
