4.2.4.4 Editing an Address Mapping Rule
To edit an address mapping rule, click the rule’s link in the NAT Address
Mapping Rules screen to display the screen shown next.
Type:
1-1: One-to-one mode maps one local IP address to one global IP address. Note
that port numbers do not change for the One-to-one NAT mapping type.
M-1: Many-to-One mode maps multiple local IP addresses to one global IP
address. This is equivalent to Many to One (i.e., PAT, port address
translation). M-M Ov (Overload): Many-to-Many Overload mode maps
multiple local IP addresses to shared global IP addresses.
MM No (No Overload): Many-to-Many No Overload mode maps each local IP
address to unique global IP addresses.
Server: This type allows you to specify inside servers of different services behind
the NAT to be accessible to the outside world.
Local Start IP: This is the starting Inside Local IP Address (ILA). Local IP
addresses are N/A for Server port mapping.
Local End IP: This is the end Inside Local IP Address (ILA). If your rule is for all
local IP addresses, then enter 0.0.0.0 as the Local Start IP address and
255.255.255.255 as the Local End IP address. This field is N/A for One-to-one
and Server mapping types.
