Virtual Server: User can specify some services to be visible from outside users. The router can detect 
incoming service request and forward it to the specific local computer to handle it. For example, user can 
assign a PC in LAN acting as WEB server inside and expose it to the outside network. Outside user can 
browse inside web server directly while it is protected by NAT. A DMZ host setting is also provided to a 
local computer exposed to the outside network, Internet. 

Firewall:  Supports SOHO firewall with NAT technology. Automatically detects and blocks the Denial of 
Service (DoS) attack. The URL-blocking, packet filtering and SPI are also supported. The hacker’s attack 
will be recorded associated with timestamp in the security logging area. More firewall features will be 
added continually, please visit our web site to download latest firmware. 

Dynamic Host Control Protocol (DHCP) client and server: In the WAN site, the DHCP client can get 
an IP address from the Internet Server Provider (ISP) automatically. In the LAN site, the DHCP server 
can allocate multiple clients IP addresses and distribute them including IP address, subnet mask as well 
as DNS IP address to local computers. It provides an easy way to manage the local IP network.
