Command Reference
[3Com-Serial0/0/0] undo nat server protocol tcp global 202.110.10.11
8070 inside 10.110.10.11 ftp
Specify an outside address as 202.110.10.10, and map the ports ranging from 1001
to 1100 to the addresses of 10.110.10.1 to 10.110.10.100 respectively to access ftp
service inside VPN vrf10. 202.110.10.10:1001 accesses 10.110.10.1 and
202.110.10:1002 accesses 10.110.10.2, etc.
[3Com-Serial0/0/0] nat server protocol tcp global 202.110.10.10 1001
1100 inside 10.110.10.1 10.110.10.100 telnet
Specify the address of the current public network interface of the router as the public
network address of NAT server. Configure FTP interface mapping of an internal server
with the IP address of 1.0.0.1 to provide service for public network users.
[3Com-Ethernet0/0/0] nat server protocol tcp global current-interface
ftp inside 1.0.0.1 ftp
Specify the IP address obtained by Dialer 0 interface as the public network address of
NAT server.

Description Through this command, you can configure some internal network servers for outside
use. The internal server can locate in the ordinary private network or in MPLS VPN. For
example, www, ftp, telnet, kpop3, dns and so on.
Up to 256 internal server conversion commands can be configured on one interface
and at most 4096 internal servers can be configured on one interface. Up to 1024
internal server conversion commands can be configured in one system. If the nat
servers are configured in the form of port range (that is, specify a port range through
configuring global-port1 and global-port2, forming a corresponding relation with the
address range of the internal hosts), then the number of internal servers will be the
same as that of the ports configured, and the max number of them are also 4096. To
ensure the normal work of NAT while configuring nat server for tftp, it is required to
configure nat outbound for tftp server in internal network.
The interface on which this command is configured is interconnected with ISP and
serves as the gateway of the internal network.
