Remote Computer Access Basics
When a computer on your network needs to access a computer on the Internet, your
computer sends your router a message containing the source and destination address and
process information. Before forwarding your message to the remote computer, your router
has to modify the source information and create and track the communication session so that
replies can be routed back to your computer.
Here is an example of normal outbound traffic and the resulting inbound responses:
1. Y
ou open a browser, and your operating system assigns port number 5678 to this
browser session.
2. Y
ou type http://www.example.com into the URL field, and your computer creates a web page
request message with the following address and port information. The request message is
sent to your router.
• Source address.
Your computer’s IP address.
• Source port
number. 5678, which is the browser session.
• Destin
ation address. The IP address of www.example.com, which your computer
finds by asking a DNS server.
• Destin
ation port number. 80, which is the standard port number for a web server
process.
3. Y
our router creates an entry in its internal session table describing this communication
session between your computer and the web server at www.example.com. Before sending
the web page request message to www.example.com, your router stores the original
information and then modifies the source information in the request message, performing
Network Address Translation (NAT):
• T
he source address is replaced with your router’s public IP address. This is necessary
because your computer uses a private IP address that is not globally unique and
cannot be used on the Internet.
• T
he source port number is changed to a number chosen by the router, such as 33333.
This is necessary because two computers could independently be using the same
session number.
Your router then sends this request message through the Internet to the web server at
www
.example.com.
4. Th
e web server at www.example.com composes a return message with the requested web
page data. The return message contains the following address and port information. The
web server then sends this reply message to your router.
Source address. The
IP address of www.example.com.
Source port number. 80,
which is the standard port number for a web server process.
Destination address. The p
ublic IP address of your router.
Destination port number. 3333
3.
5. Upon receiving the
incoming message, your router checks its session table to determine
whether there is an active session for port number 33333. Finding an active session, the
