NAT & Routing

Step 7. Setup Server Rules
Insert a virtual server rule by clicking the Insert
button.
ADVANCED SETTINGS > NAT > Virtual Servers
Step 8. Customize the Rule
Customize the rule name as the ftpServer. For
any packets with its destination IP equaling to the
WAN1 IP (61.2.1.1) and destination port
equaling to 44444, ask DFL-1500 to translate the
packet’s destination IP/port into 10.1.1.5/21.
Check the Passive FTP client? to maximize
the compatibility of the FTP protocol. This is
useful if you want to provide connectivity to
passive FTP clients. For passive FTP clients, the
server will return them the private IP address and
the port number for them to connect back to do
data transmissions. Since the private IP from
them cannot be routed to our zone, the data
connections will fail. After enabling this feature,
the DFL-1500 will translate the private IP/port into
an IP/port of its own. Thus the problem is
gracefully solved. Click Apply to proceed.
Note after setting the Virtual Server rule, please
adjust your corresponding firewall/NAT rules
manually. Or the virtual server will work
improperly.
