MTU
MTU size
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.
