Q: Can Internet users access LAN
computers?
The NetComm Cable/DSL Firewall Router
uses NAT to route all in/out band packets. All
external users can only see the IP of the
NetComm Cable/DSL Firewall Router but
cannot access LAN computers. The LAN
computers are well protected with the
NetComm Cable/DSL Firewall Router’s
natural firewall (NAT). You can allow
Internet users access to specific computers by
using the Port Forwarding, DMZ Host and
Special Application options.
Q: When should I use DMZ host?
Enable DMZ host when you want to have
unrestricted communication between your
computer and the Internet, for example,
playing Internet game (i.e. Ages of Empire) or
having multimedia conference (i.e.
NetMeeting).

Firewall Router support PPTP of VPN
packets pass through?
Yes. The NetComm Cable/DSL Firewall
Router supports single session PPTP pass
through.
Q: Does the NetComm Cable/DSL
Firewall Router series support IPsec?
Yes. The NetComm Cable/DSL Firewall
Router supports single session IPsec pass
through.
