Firewall

Security - Firewall (Router Mode Only)
Basic Rules
Enable to use any of the quick filters. Preconfigured quick filters include:
Prohibit NBT and Microsoft-DS routing
Enabling this blocks communication using these protocols from the WAN side to the
LAN side or from the LAN side to the Internet. You can configure this with PPPoE if you
select Use PPPoE client or Use IP Unnumbered for the method of acquiring IP Address, or if
Easy Setup identified a PPPoE connection during setup.
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 email, FTP, and 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 for the
method of acquiring an IP address, or if Easy Setup identified a PPPoE connection during
setup.
