Ok i have listed below the basic steps involved. Please note these steps are a for a specific version of the Norton Firewall. Your own version
may
differ slightly from the information listed below.
Communications: protocols and ports
The Add Rule dialog box for Communications provides two choices, the protocol and the ports
The appropriate protocol to select depends on the rule. The protocol choices are:
• TCP
• UDP
• TCP and UDP
The choices for ports are:
• "Any type of communication." This option applies the rule to all ports.
• "Only the types of communication identified below." This option applies the rule only to the ports that you specify.
To apply the rule to all ports
1. Select the protocol.
2. Select "Any type of communication."
3. Click Next.
To apply the rule only to specified ports
1. Select the protocol.
2. Select "Only the types of communication identified below."
3. Click Add. You see the Specify Ports window.
4. Select the type of Locality:
•
Local
. This option indicates the port number for service or process that is at your computer. For instance, for an incoming communication, the local port is the destination port. For an outgoing communication, the local port is the source port.
•
Remote
. This option indicates the port number for the service or process that is at the other computer. For an incoming communication, the remote port is the source port. For an outgoing communication, the remote port is the destination port.
5. Select one of the following options under "Filter by":
• "Known ports from list." NIS and NPF maintain a list of commonly used ports. When you select the "Known ports from list" option, you see a list of individual ports:
a. Select each port to which you want this rule to apply. Do this for as many ports as you want to include.
b. Click OK. The selected ports are added to the list of ports that this rule applies to
c. Click Next.
• "
Individually specified ports
." When you select the "Individually specified ports" option, you see a box in which you can list the ports that you want the rule to apply to.
a. Type the port numbers in the box. Separate the ports by a space. The following example uses the ports 22, 5631, 5632, and 65301:
b. Click OK. The selected ports are added to the list of ports that this rule applies to, as in the following example:
c. Click Next.
• "Port range." Use this option to specify a contiguous range of ports. For instance, the range 1417-1420 includes the port number 1417, 1418, 1419, and 1420. When you select the "Port range" option, you see two boxes.
a. Type the lowest port number in the range in the "Enter the starting port" box.
b. Type the highest port number in the range in the "Enter the ending port" box. The following example uses the range 1417-1420.
c. Click OK. The selected ports are added to the list of ports that this rule applies to.
d. Click Next.
I hope that helps you a little. Sorry if it contains lots of Jargon, but i have tried to keep it as close as possible to what you are likely to actually see on your screen.
