Disable Firewall Select the Disable Firewall checkbox to disable all firewall
functions on the
access point. This includes firewall filters, NAT,
VPN, content filtering, and subnet access. Disabling the
access
point
firewall makes the access point vulnerable to data attacks
and is not recommended during normal operation if using the WAN
port.
NAT Timeout Network Address Translation (NAT) converts an IP address in one
network to a different IP address or set of IP addresses in a
different network. Set a NAT Timeout interval (in minutes) the
access point uses to terminate the IP address translation process
if no translation activity is detected after the specified interval.
SYN Flood Attack
Check
A SYN flood attack requests a connection and then fails to
promptly acknowledge a destination host's response, leaving the
destination host vulnerable to a flood of connection requests.
