Reference Manual for the 54 Mbps Wireless Router WGR614 v4
6-4 Advanced Configuration
December 2003
Some online games and videoconferencing applications are incompatible with NAT. The WGR614
v4 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 PC can run the
application properly if that PC’s IP address is entered as the default in the PORTS Menu. If one
local PC acts as a game or videoconferencing host, enter its IP address as the default.
Configuring WAN Setup Options
The WAN Setup options let you configure a DMZ server, change the MTU size and enable the
router to respond to a Ping on the WAN port. These options are discussed below.
Figure 6-2: WAN Setup menu.
• 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 WGR614 v4. However, certain
communications functions like VPN may require turning off the SPI feature.
