H3C S9500 Series Routing Switches
host-addr1 host-addr2: Specifies an address scope of internal hosts that corresponds
to the address range of external service port numbers. host-addr2 must be bigger than
host-addr1. The number of the address scope must be the same as the number of
external service ports.
slot-no: Specifies number of the slot in which the NAT service board resides.
Description
Use the nat server command to define mapping relationships from public addresses
and external service port numbers to internal addresses and internal service port
numbers.
After the configuration, by using the address and port number defined by the
global-addr and the global-port parameters, you can access the internal server with the
address and port number specified by the host-addr and host-port parameters.
Use the undo nat server command to cancel the mapping table.
The keywords icmp, tcp and udp are the protocol types carried by IP, which can be
represented by 1, 6 and 17 respectively. You can select only one protocol type in a
command. If no port is specified in the command, an AnyServer is configured.
An AnyServer is used to define mapping relationship between a public address and the
internal address of a server of the specified protocol type. Through this mapping, hosts
on the public network and private network can access each other.
