Controlling access to protected computers

Control how users access the Internet

Norton Personal Firewall supports most Internet connection methods

without needing additional configuration.

If you access the Internet via a cable or DSL router

Norton Personal Firewall works behind a cable or DSL router and adds to

the protection provided by the router. In some cases, you might want to

reduce the protection provided by the router so that you can use programs

like NetMeeting or Microsoft Messenger. Norton Personal Firewall also

provides features that might not be available with cable and DSL routers,

such as privacy protection.

If multiple computers share a single Internet connection

Norton Personal Firewall works with most Internet connection sharing

programs. To protect your network from many outside attacks, install

Norton Personal Firewall on the gateway computer. For maximum

protection against Trojan horses or other problem programs that initiate

outbound connections, install Norton Personal Firewall on all computers

that share the connection.

Control how outside users access your network

Norton Personal Firewall can protect computers while still allowing outside

users to access servers on your network. To run servers on protected

computers, you may have to create firewall rules that let outside users

connect to certain ports. For maximum security, only create these rules on

the computers running your servers.

If you run Symantec pcAnywhere

See “Change an

existing firewall

rule” on page 83.

You should have no problems using Symantec pcAnywhere as either a

client or host with Norton Personal Firewall. For maximum protection, if

you run a Symantec pcAnywhere host, edit the rule to limit its use to only

the computers with which you use it. This, and Symantec pcAnywhere

passwords, provide maximum security.
