A user-configurable firewall and method in which a user-changeable security setting for a client computer is maintained by an access server through which a user accesses the public network. The us er- changeable security setting can be used to specify which outside computers or network devices may access the client computer and what type of access to the client computer is allowed. If an attempt to access the client computer is made, the user- configurable security setting is checked to determine if the attempted access is allowed by the current security setting. If the attempte d access is allowed by the current security setting, access is allowed to the client computer; otherwise, access is not allowed. If the user changes the user-configurable security setting, the changes to the user-configurable security settings are provided to the acces s server. <IMG>
