Nat Pinhole Commands - Motorola Netopia Administrator's Handbook

NAT Pinhole commands

NAT pinholes let you pass specific types of network traffic through the NAT interfaces on the Motorola Netopia®
Gateway. NAT pinholes allow you to route selected types of network traffic, such as FTP requests or HTTP (Web)
connections, to a specific host behind the Motorola Netopia® Gateway transparently.
To set up NAT pinholes, you identify the type(s) of traffic you want to redirect by port number, and you specify the
internal host to which each specified type of traffic should be directed.
The following list identifies protocol type and port number for common TCP/IP protocols:
◆
FTP (TCP 21)
◆
telnet (TCP 23)
◆
SMTP (TCP 25),
◆
TFTP (UDP 69)
set pinhole name name protocol [ tcp | udp ]
Specifies the identifier for the entry in the Gateway's pinhole table. You can name pinhole table entries sequen-
tially (1, 2, 3), by port number (21, 80, 23), by protocol, or by some other naming scheme. Specifies the type of
protocol being redirected.
set pinhole name name ext-port-range [ 0 - 49151 ]
Specifies the first and last port number in the range being translated.
set pinhole name name int-addr ipaddr
Specifies the IP address of the internal host to which traffic of the specified type should be transferred.
set pinhole name name int-start-port [ 0 - 65535 ]
Specifies the port number your Motorola Netopia® Gateway should use when forwarding traffic of the specified
type. Under most circumstances, you would use the same number for the external and internal port.
