Linkskey LKR-604 - Manual (Page 5)

LKR-604
• DMZ Host Support
Allows a networked computer to be fully exposed to the Internet. This
function is used when NAT or Firewall security prevent the special
application feature from functioning correctly.
• Virtual Private Network (VPN)
The LKR-604 supports most commonly used VPN protocols — PPTP
and IPSec. These protocols allow remote users to establish a secure
VPN connection over the Internet to their corporate network. If your
Internet service provider supports PPTP and IPSec protocols, then
these protocols can be used to create an authenticated and encrypted
VPN tunnel for passing secure data over the Internet (i.e., a traditionally
shared data network).
