Chapter 5 Web-based Interface Configuration for Compex SGX3226

The Internet makes two transport protocols available to its applications,

namely TCP and UDP.

Transmission Control Protocol

(TCP)

For building a reliable

communications stream on top of

the unreliable packet Internet

Protocol (IP). TCP is the protocol

that supports nearly all Internet

applications.

User Diagram Protocol (UDP)

A connectionless protocol that

runs on top of IP networks.

UDP/IP provides very few errors

recovery services, offering instead

a direct way to send and receive

datagrams over an IP network. It is

used primarily for broadcasting

messages over a network.

5.6.3 Filtering Setting

Compex SGX3226 allows Packet Filtering rules be defined based on three

factors, Source IP Address, TCP Port and Time. IP Packet Filtering

examines the outgoing packets and decides whether to bypass or to block

them. After the Packet Filtering rules have been defined, the users may

select to bypass or to block the outgoing packets that do not match the rules.

For example, assume that a rule has been defined as "TCP Port 23 (used by

TELNET) from any IP on any day at any time". If the “forwarded” radio

button is selected, all outgoing packets will be sent except TELNET session.

If the blocked radio button is selected, all outgoing packets will be blocked

except TELNET session.

Click on Filtering section at the Configuration window and the GUI will

appear as shown:

1 2 ... 36 37 38 39 40 41 42 43 44 45 46 ... 89 90
