6.10.1 Configuring LAN to WAN Access
The access point LAN can be configured to communicate with the WAN side of the access point. Use
the Subnet Access screen to allow/deny access to the access point WAN protocols, specify names
and properties for existing protocols and enable pre-configured protocols (FTP, TFTP, Telnet ect.).
To configure access point subnet access:
Source Routing
Check
A source routing attack specifies an exact route for a packet's
travel through a network, while exploiting the use of an
intermediate host to gain access to a private host.
Winnuke Attack
Check
A "Win-nuking" attack uses the IP address of a destination host to
send junk packets to its receiving port.
FTP Bounce Attack
Check
An FTP bounce attack uses the PORT command in FTP mode to gain
access to arbitrary ports on machines other than the originating
client.
IP Unaligned
Timestamp Check
An IP unaligned timestamp attack uses a frame with the IP
timestamp option, where the timestamp is not aligned on a 32-bit
boundary.
Sequence Number
Prediction Check
A sequence number prediction attack establishes a three-way TCP
connection with a forged source address. The attacker guesses the
sequence number of the destination host response.
Mime Flood Attack
Check
A MIME flood attack uses an improperly formatted MIME header
in "sendmail" to cause a buffer overflow on the destination host.
Max Header Length Use the Max Header Length field to set the maximum allowable
header length (at least 256 bytes).
Max Headers Use the Max Headers field to set the maximum number of
headers allowed (at least 12 headers).
