Different firewall models provide various numbers of
copper and fiber optic ports, which operate at different speeds.
A virtual wire can bind two Ethernet ports of the same type (both
copper or both fiber optic), or bind a copper port with a fiber
optic port. By default, the
Link Speed
of
copper ports on the firewall is set to
auto
,
which means the firewall automatically negotiates their speed and
transmission mode (
Link Duplex
). When you
Configure
Virtual Wires, you can also select a specific
Link
Speed
and
Link Duplex
but the
values for these settings must be the same for both ports in any
single virtual wire.
