Network Address Translation (NAT) Pinhole Settings
NAT pinholes let you pass specific types of network traffic through the NAT inter faces on
the 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 Netopia
Gateway transparently.
To set up NAT pinholes, you identify the type(s) of traffic you want to redirect by por t num-
ber, and you specify the internal host to which each specified type of traffic should be
directed.
The following list identifies protocol type and por t number for common TCP/IP protocols:
• FTP (TCP 21)
• telnet (TCP 23)
• SMTP (TCP 25),
• TFTP (UDP 69)
• SNMP (TCP 161, UDP 161)
set pinhole name name
Specifies the identifier for the entr y in the router's pinhole table. You can name pinhole
table entries sequentially (1, 2, 3), by por t number (21, 80, 23), by protocol, or by some
other naming scheme.
set pinhole name name protocol-select { tcp | udp }
Specifies the type of protocol being redirected.
set pinhole name name external-port-start [ 0 - 49151 ]
Specifies the first por t number in the range being translated.
