Network Address Translation (NAT) Pinhole Settings
NAT pinholes let you pass specific types of network traffic through the NAT interfaces 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 port 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 port number for common TCP/IP protocols:
• FTP (TCP 21)
• telnet (TCP 23)
• SMTP (TCP 25),
• TFTP (UDP 69)
• SNMP (TCP 161, UDP 161)
