IP addresses pool. Then, you can define FTP to use address X
to reach computer A and address Y to reach computer B.
Additionally, port forwarding enables you to redirect traffic to a
different port instead of the one to which it was designated. For
example, if you have a Web server running on your PC on port
8080 and you want to grant access to this server to any one
who accesses DSL router via HTTP.
To accomplish this, do as follows:
Step 1 Define a port forwarding rule for the HTTP service, with
the PC IP or host name.
Step 2 Specify 8080 in the Forward to Port field.
All incoming HTTP traffic is forwarded to the PC running the
Web server on port 8080. When setting a port forwarding
service, ensure that the port is not used by another application,
which may stop functioning. A common example is when using
SIP signaling in Voice over IP, the port used by the gateway
VoIP application (5060) is the same port, on which port
forwarding is set for LAN SIP agents.
Note: Some applications, such as FTP, TFTP, PPTP and H323,
require the support of special specific application level
gateway (ALG) modules in order to work inside the home
network. Data packets associated with these applications
contain information that allows them to be routed
correctly. An ALG is needed to handle these packets and
ensure that they reach their intended destinations. DSL
router is equipped with a robust list of ALG modules in
order to enable maximum functionality in the home
network. The ALG is automatically assigned based on
the destination port.
Virtual servers are configured for this purpose.
