This is very useful to avoid Internet intruder/hacker from probing the
computer. Most likely, the hacker will not start to attack due to no PING
response.
2.
This function allows the administrator to configure the Wireless Router
from the outside Internet with browser directly. In order to reserve HTTP
service (port 80), which is used for virtual servers, the remote web
administration function utilizes another port 64511 instead. (e.g.
http://211.79.244.45:64511 )
3.
This function is used to inhibit some LAN clients (by IP address) from
accessing Internet resources. Since all LAN client are recognized by their
IP addresses, regardless of if the LAN client’s IP address is assigned by
DHCP server or manual setting, this function always works well.
4.
This function allows the administrator to inhibit LAN users from using some
Internet services for management purposes.
For example, if the Wireless Router is used in a SOHO environment and
the administrator wants to inhibit LAN users from using Telnet services
(like BBS, on-line chat), then it is easily achieved by blocking all packets to
service port 23.
Another example would be blocking service port 110 (POP3) which will
inhibit LAN users from checking/retrieving outside Internet e-Mail
accounts periodically. This is very useful when the WAN connection type is
Dial-On-Demand (like PPPoE/PPP). Then, the Wireless Router can auto-
disconnect at normal conditions. Otherwise the periodic e-Mail checking
from the LAN user will cause the Wireless Router to keep the WAN
connection alive forever. Therefore, in this situation, the LAN user can only
use e-Mail servers inside the network. (if a POP3 server exist in LAN).
