5.1.6 NAT pinhole page

The NAT pinhole page is used to make servers located in a LAN visible
to the WAN through a VCC. It allows fixed NAPT mapping between a
WAN/VCC IP address/port number and an internal LAN IP
address/port number. Separate entries must be created for TCP and
UDP ports.
The standard port numbers for the most common protocols are:
D
HTTP (Hypertext Transfer Protocol) is TCP port 80
D
FTP (File Transfer Protocol) is TCP port 21
D
SMTP (Simple Mail Transfer Protocol) is TCP port 25
D
NNTP (Network News Transfer Protocol) is TCP port 119

1. Enter a name for the pinhole entry. Select the protocol. Enter the
External Port Start and External Port End numbers. These define
the available range of allowed external ports (port number in WAN
interface). Enter Internal IP address (server IP address in LAN)
and Internal Port number (server port number in LAN). The
Internal Port number is the start of the internal port range.
2. Click Add.
3. Repeat until each server's information is filled.
4. To remove an entry, click delete.
