Overview

D-Link 22

Step 6. Setup IP for the FTP

Server

Assign an IP of 10.1.1.5/255.255.255.0 to

the FTP server under DMZ1. Assume the

FTP Server is at 10.1.1.5. And it is listening

to the well-known port (21).

N/A

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 address equaling to the

WAN1 IP (61.2.1.1) and destination port

equaling to 44444. DFL-1500 will 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 at DMZ

will return them the private IP address

(10.1.1.5) and the port number for the

clients to connect back for data

transmissions. Since the FTP clients at the

WAN side cannot connect to a private-IP

(ex.10.1.1.5) through the internet. The data

connections would be 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.
