keniars,
Simply put the command "ip nat inside source list 101 interface
Ethernet1/0 overload"
means nat/translate any packet that matches access-list 101 to the ip
address in this case
on ethernet0. Since etherenet0 is the only global address that will be
used(think of it as being the only address in a pool if you had configured
one), the keyword "overload" is telling nat to use the address on ethernet0
as the only address for any number of local addresses.
overload - (Optional) Enables the router to use one global address for many
local addresses. When overloading is configured, each inside host's TCP or
UDP port number distinguishes between the multiple conversations using the
same local IP address.
