This field is normally optional. Only one DNS
address is required for a functional Internet con-
nection, but using a second DNS address pro-
vides more stability.
MTU:
Maximum Transmission Unit - you may need to
change the MTU for optimal performance with
your specific ISP. 1400 is the default MTU.
MAC Address:
The default MAC address is set to the Internet
port's physical interface MAC address on the
broadband router. It is not recommended that
you change the default MAC address unless
required by your ISP. You can use the Clone Your
PC's MAC Address button to replace the
Internet port's MAC address with the MAC
address of your Ethernet card.
