WAN and LAN Configuration

3.

Select the PC to be used as the DMZ Server for this IP address. 

•

Click Apply. 

Note: 

•

All incoming traffic to that IP address will be sent to the selected PC. 

•

Out-going traffic from the selected PC will use the IP address you entered, not the default 
WAN IP address. 

•

If you only have one (1) Internet IP address, you cannot use the Multi-DMZ feature, only the 
Default DMZ Server setting above. 

If you want the FVL328 to respond to a ping from the Internet, click this check box. This should 
only be used as a diagnostic tool, since it allows your firewall to be discovered. Again, like the 
DMZ server, this can be a security problem. You shouldn't check this box unless you have a 
specific reason to do so. 

The normal MTU (Maximum Transmit Unit) value for most Ethernet networks is 1500 bytes or 
1492 Bytes for PPPoE connections. For some ISPs you may need to reduce the MTU. But this is 
rarely required, and should not be done unless you are sure it is necessary for your ISP connection. 
Any packets sent through the firewall that are larger than the configured MTU size will be 
repackaged into smaller packets to meet the MTU requirement. 

To change the MTU size:

1.

Under MTU Size, select Custom.

2.

Enter a new size between 64 and 1500.

3.

Click Apply to save the new configuration.

In most cases, your router can automatically determine the connection speed of the Internet 
(WAN) port. If you cannot establish an Internet connection and the Internet LED blinks 
continuously, you may need to manually select the port speed.
