Installing a PIX 506
• MTU size—The maximum transmission unit (MTU) size for each network interface. You only need
to specify a value if you want to set an MTU size that differs from the default
(1,500 bytes/block for Ethernet; 8,192 bytes/block for Token Ring and FDDI).
In addition, you should determine the IP address of the outside default router and your network topology
and security policy. We recommend that you take a few minutes to draw a diagram of your network with
IP addresses, indicating which computers you are protecting, and which switches, routers, and hosts are
on each network.
