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.
