Settings - IP Filtering
IP filtering is simply a mechanism that decides which types of IP datagram’s will be processed
normally and which will be discarded. By discarded we mean that the datagram is deleted and completely
ignored, as if it had never been received. You can apply many different sorts of criteria to determine which
datagram’s you wish to filter; some examples of these are:
Protocol type: TCP, UDP, ICMP, etc.
Socket number (for TCP/UPD)
Datagram type: SYN/ACK, data, ICMP Echo Request, etc.
Datagram source address: where it came from
Datagram destination address: where it is going to.
It is important to understand at this point that IP filtering is a network layer facility. This means it
doesn't understand anything about the application using the network connections, only about the
connections themselves. The IP filtering rule set is made up of many combinations of the criteria listed
previously.
Use firewall option to set IP addresses from which is possible remote access on the PRESTO
Advanced Router.
Demilitarized Zone (DMZ) allows one IP Address to be exposed to the Internet. Because some applications
require multiple TCP/IP ports to be open, DMZ provides this function by forwarding all the ports to one
computer at the same time. In the other words, this setting allows one local user to be exposed to the
Internet to use a special-purpose services such as Internet gaming, Video-conferencing and etc. It is
recommended that you set your computer with a static IP if you want to use this function.
