VoIPBox BRI Version 18.0.002 Page 56
The following NAT settings are for a system in which PPPoE
(DSL) is used toward the Internet. The local network range
192.168.1.0 Class C is translated with the following rules:
|
The proxy mode is used for FTP.
|
All other TCP and UDP packets are mapped to the exter-
nal ports 40000 to 60000.
|
There are no special rules for any other services.
|
Incoming requests to port 80 and 443 in the public IP ad-
dress 192.168.1.100 are redirected to ports 80 and 443 in
the local IP address 192.168.1.100.
4.1.6 PPPoE Configuration
The protocol Point-to-Point over Ethernet is used for DSL
communication with the DSLAM. That means the system can
connect directly with the carrier network and terminate VoIP
traffic directly.
<port> Defines the port number.
<local ip address/mask> The IP address is entered in decimal notation, followed by
a slash (/) and the netmask in bit notation. The entire local
network range is configured.
<protocol> Defines the protocol. tcp and udp are possible.
watch=<interface 1> <interface 2> ... <interface n>
Enter all interfaces that you have configured. If an interface is activated, the NAT table is
resetted to ensure correct IP address translation.
