BM-525 Bandwidth Management Gateway User’s Manual
Chapter 1: Introduction
The BM-525 is specifically designed for SOHO networks. It has built-in one 10/100Mbps Ethernet
LAN, DMZ, and WAN ports. No broadband router is required for users with only one public IP
address. It also supports virtual server, Multi-DMZ, and dynamic DNS functions that are very
useful for our customers to share local resources with Internet users.
For bandwidth management, packets can be classified based on IP address, IP subnet, and
TCP/UDP port number. The device has more than 40 of the most common protocols such as H.323,
Oracle, HTTP, FTP, and so on for easy definition. The administrator can then define policies to
ensure committed and maximum bandwidth levels for inbound and outbound traffic in each class.
The administrator can also define three priority levels for each policy to ensure high priority packets
receive the maximum available bandwidth. In addition, each policy can have a schedule defined for
when the policy is activated or inactivated in increments of 30 minutes.
Both the NAT mode and DMZ mode are supported, and therefore can maintain the existing network
infrastructure without reconfiguring. The BM-525 provides policy-based firewall protection and
several hacker protections to prevent hackers’ attack. Besides, the comprehensive alarm and log
function allow the network manager to easily enhance the security of local network.

2.1 Administration
“System” is the managing of settings such as the privileges of packets that pass through the
BM-525 and monitoring controls. The System Administrators can manage, monitor, and configure
BM-525 settings. But all configurations are “read-only” for all users other than the System
Administrator; those users are not able to change any setting of the BM-525.

BM-525 Bandwidth Management Gateway User’s Manual
NAT Mode:
It allows Internal Network to set multiple subnet address and connect with the Internet through
different WAN IP Addresses. For example, the lease line of a company applies several real IP
Addresses 168.85.88.0/24. The company is divided into R&D department, service, sales
department, procurement department, and accounting department. The company can
distinguish each department by different subnet for the purpose of managing conveniently. The
settings are as the following：
1. R&D department subnet：192.168.1.1/24 (LAN) ÅÆ 168.85.88.253 (WAN)
2. Service department subnet： 192.168.2.1/24 (LAN) ÅÆ 168.85.88.252 (WAN)
3. Sales department subnet： 192.168.3.1/24 (LAN) ÅÆ 168.85.88.251 (WAN)
4. Procurement department subnet
192.168.4.1/24 (LAN) ÅÆ 168.85.88.250(WAN)
5. Accounting department subnet
192.168.5.1/24 (LAN) ÅÆ 168.85.88.249(WAN)
The first department (R&D department) had set while setting interface IP; the other four ones have
to be added in Multiple Subnet. After completing the settings, each department uses the different
WAN IP Address to connect to the Internet. The settings of each department are as following:
Service Sales Procurement Accounting
IP Address 192.168.2.2~254 192.168.3.2~254 192.168.4.2~254 192.168.5.2~254
Subnet Netmask 255.255.255.0 255.255.255.0 255.255.255.0 255.255.255.0
Gateway 192.168.2.1 192.168.3.1 192.168.4.1 192.168.5.1
Routing Mode:
It is the same as NAT mode approximately but does not have to correspond to the real WAN IP
address, which let internal PC to access to Internet by its own IP (External user also can use the
IP to connect with the Internet).
