Built-in VPN Endpoint
Full VPN Endpoint with support for up to 50 VPN tunnels using the IPsec encryption protocol.
Authoritative DNS to IP Gateway
The XC-DPG603 is an authoritative DNS to IP gateway that resolves a domain name to its respective IP
addresses. This new capability allows for inbound failover and load balancing for servers located behind
the gateway. Using dual WAN ports simultaneously increases available bandwidth for both uploads and
download requests. You can set load balance type by Packets, Bytes rx+tx and Sessions.
Multiple Connection Methods
All popular DSL and Cable Modems and connection methods are supported, including Fixed IP, Dynamic
IP, PPPoE, even multiple-session PPPoE.
2 x 10/100 WAN Ports
The XC-DPG603 incorporates dual 10/100 WAN ports, complete with auto-crossover for easy
connection to an existing network. All popular DSL and Cable Modems and connection methods are
supported, including Fixed IP, Dynamic IP, PPPoE, even multiple-session PPPoE.
4-Port 10/100 Switch
The XC-DPG603 incorporates a 4-port 10/100 N-Way Ethernet Switch, complete with auto crossover for
easy connection to an existing network.
Automatic Fail-over
If one broadband connection goes down all traffic is automatically re-routed through the second
broadband connection.
Stateful Packet Inspection (SPI) Firewall
Protects your network using advanced SPI against malicious and DDoS attacks.
Advanced NAT features
Access Filters, DMZ, DDNS, Remote Management, Dynamic or Static Routing, Special Applications,
Virtual Servers, SNMPv1.
Access Filter
Gain fine control over the Internet access and applications available to LAN users with a powerful URL
Blocking Engine. Five (5) user groups are available, and each group can have different access rights.
Block URL
Use this feature to block access to undesirable Web sites by LAN users. You can even have different
settings for different groups of PCs.
Figure 2. Load Balancing
Load Balance two concurrent broadband connections in any combination to expand a
network’s bandwidth to the Internet. The XC-DPG603 supports T1, xDSL, Cable, and Satillite
broadband connections.
Active connection from the ISP
The XC-DPG603 load balances
both inbound and outbound
traffic requests.
Figure 3. Automatic Fail-over
In the event of one connection going down, all traffic is re-routed to the second WAN
port utilizing the live broadband connection from the second ISP. This provides true
redundancy to ensure a network remains connected to the Internet.
Active connection from the ISP
Inactive connection from the ISP
All incoming and outgoing
traffic from a LAN has an
uninterrupted connection to
the Internet when one of the
two connections fail.

A client computer makes a request to
access www.(yourdomain).com.
The request goes to the ISP’s DNS
server and the DNS server replies
with the IP address of the DNS
responsible for that domain.
The request is then processed by the
Authoritative DNS of that domain
and provides the IP address of the
specified server.
The client can then access the web
server.
