• Point-to-Point Tunneling Protocol (PPTP)
Typically used as a protocol for virtual private networks. This protocol is used by some
Russian ISPs for connecting remote hosts to the Internet over an ADSL connection.
• Dynamic DNS
Dynamic DNS services allow remote users to find your network using a domain name when
your IP address is not permanently assigned. The modem router contains a client that can
connect to many popular Dynamic DNS services to register your dynamic IP address.
• Universal Plug and Play (UPnP)
UPnP is a networking architecture that provides compatibility between networking
technologies. UPnP compliant routers provide broadband users at home and small businesses
with a seamless way to participate in online games, videoconferencing and other peer-to-peer
services.

The ADSL Modem Wireless Router provides a secure encrypted connection between your local
area network (LAN) and remote networks or clients. It includes the following VPN features:
• Supports 5 VPN connections.

The ADSL Modem Wireless Router supports standard Manual or IKE keying methods,
standard MD5 and SHA-1 authentication methods, and standard DES and 3DES encryption
methods. It is compatible with many other VPN products.

Auto Sensing and Auto Uplink™ LAN Ethernet Connections
With its internal 4-port 10/100 switch, the DG834GSP can connect to either a 10 Mbps standard
