Disable SPI Firewall

This check box is usually cleared so that the firewall protects your 
LAN against port scans and denial of service attacks. This check box 
should be selected only in special circumstances.

Default DMZ Server

This feature is sometimes helpful when you are using some online 
games and videoconferencing. Be careful when using this feature 
because it makes the firewall security less effective. See 

Respond to Ping on Internet

If you want the router to respond to a ping from the Internet, select 
this check box. This should be used only as a diagnostic tool, since it 
allows your router to be discovered. Do not select this check box 
unless you have a specific reason to do so.

MTU Size

Maximum Transmit Unit (MTU) value. For most Ethernet networks 
this is 1500 bytes, or 1492 bytes for PPPoE connections, or 1436 
bytes for PPTP connections.

NAT Filtering

This is set to Secured to provide a secure firewall to protect 
computers on the LAN from attacks from the Internet. The Open 
setting is less secure.

Disable SIP ALG

Some VoIP applications do not work well with SIP ALG. Selecting 
this check box might help your VoIP devices create or accept a call 
through the router.
