Remote Management

This chapter introduces remote management and explains how to implement it.

5.1 Demands

Administrators may want to manage the DFL-1500 remotely from any PC in LAN_1 with HTTP at port 8080, and from WAN_PC

with TELNET. In addition, the DFL-1500 may be more secure if monitored by a trusted host (PC1_1). What is more, the DFL-1500

should not respond to ping to hide itself. The remote management function in DFL-1500 devices is implemented by hidden Firewall

rules.

5.2 Methods

1. Only allow management by WAN_PC (140.2.5.1) at the WAN1 side.

2. Administrators can use browsers to connect to

http://192.168.40.254:8080 for management.

3. Allow SNMP monitoring by PC1_1 (192.168.40.1) at the LAN1 side.

4. Do not respond to ICMP ECHO packets at the WAN1 side.

5.3 Remote Management Access Methods

Configuring management access for an interface connected to the Internet allows remote administration of the DFL-1500 unit from

any location on the Internet. Allowing management access from the Internet could compromise the security of your DFL-1500 unit.

You should avoid allowing management access for an interface connected to the Internet unless this is required for your

configuration. To improve the security of a DFL-1500 unit that allows remote management from the Internet, add secure

administrative user passwords, change these passwords regularly, and only enable secure management access using HTTPS or SSH.
