• Connect Automatically, as Required
Normally, this option should be Enabled, so that an Internet connection will be made
automatically, whenever Internet-bound traffic is detected. In locations where Internet access
is billed by the minute, if this causes high connection costs, you can disable this setting.
If disabled, you must connect manually, using the sub-screen accessed from the Router Status
menu “Show WAN Status” screen.
• Disable SPI Firewall
Normally, this option should be Enabled, so that your local network will be protected by the
Stateful Packet Inspection (SPI) firewall included in the TA612V. However, certain
communications functions like VPN may require turning off the SPI feature.
• Setting Up a Default DMZ Server
The default DMZ server feature is helpful when using some online games and
videoconferencing applications that are incompatible with NAT. The router is programmed to
recognize some of these applications and to work properly with them, but there are other
applications that may not function well. In some cases, one local computer can run the
application properly if that computer’s IP address is entered as the default DMZ server.
