Most security features can be configured on the Security page. It is
recommended you change the default password for ACEmanager.
Port Forwarding and DMZ
To add a rule, fill in the outside port (ie, 8080), the protocol (TCP or
UDP), the host (or internal) IP, and the private port (the port on the
inside of the network). Some cellular carriers restrict port access.
Check with your cellular carrier if you have problems setting this up.
To add more rules, click on the Add More button. To remove a rule,
click on the 'X' button that is next to the rule.

Command Description
Port Forwarding
Enabed
Disabled or Enabled. Disables or Enables port forwarding rules.
DMZ IP IP address of a DMZ. The Helix allows a single client to connect to the
Internet through a demilitarized zone (DMZ). The DMZ is particularly useful
for certain services like VPN, NetMeeting, and streaming video that may not
work well with a NAT router. DMZ host is unavailable if IP passthrough is
enabled.
DMZ Enabled OFF or ON. Enables or disables the DMZ on the Helix. The Helix allows a
single client to connect to the Internet through a demilitarized zone (DMZ).
Note: All security features are inactive if DMZ is enabled.
Note: Because DMZ traffic does not pass through the NAT router, the DMZ
host is fully exposed to the Internet without the protection of the Helix firewall.
If the DMZ is used, this can present a security risk to the DMZ host client.
