When the protocol type is not udp (with a protocol number of 17) or tcp (with a protocol number of 6),
you can configure one-to-one NAT between an internal IP address and an external IP address only, but
cannot specify port numbers.
Examples
# Allow external users to access the internal Web server 10.110.10.10 on the LAN through
http://202.110.10.10:8080, and the internal FTP server 10.110.10.11 in MPLS VPN vrf10
through ftp://202.110
.10.10/. Assume that the interface Serial 2/1/0 is connected to the external
network.

MPLS VPN vrf10 through the public address of 202.110.10.10 and port numbers from 1001 to 1100. As
a result, a user can Telnet to 202.110.10.10:1001 to access 10.110.10.1, Telnet to 202.110.10.10:1002 to
access 10.110.10.2, and so on.
