Chapter 4 Configuration
Parameter Meaning
Reject ident Requests
Enabling this option will answer IDENT requests from the Internet
side with corresponding rejection packets. Enable this option if
you experienced slow transfer speeds for network applications
such as mail, ftp or web browsing. If you have configured transfer
of IDENT requests to the LAN side computer in the address
translation settings (DMZ or TCP port 113), then that setting has
higher priority, and overrides this setting.
Block ping from Internet
If this is enabled, the AirStation will not respond to pings from the
Internet side. You can configure this with PPPoE if you select [Use
PPPoE client] or [Use IP unnumbered] in Method of Acquiring IP
address (page 25), or if Easy Setup identified a PPPoE connection
during setup.
