At home we have a cable modem connected to a wireless router (hardware firewall & WEP is enabled), the main desktop is hardwired to the router. My sons desktop, my wifes notebook, and my notebook connect to the network via wireless cards. As all internet traffic goes through the wireless routers hardware firewall, do I need to enable XP's Internet Connection Firewall on the computers that connect wireless? OK a step further, we use the notebooks at work and campus to connect to the internet via the wireless access points there. Should it be enabled for that? I would assume both campus and work have a firewalled internet connection already right? lastly, what about the rarely used dial up connection on the notebooks? A guy I work with told me basically I don't have to worry about it.. He said the hardware firewall covers me at home. School and work are covered because I am not connecting directly to the internet, but through a firewalled network. The dial up connection could possibly use the ICF but it is seldom used and is not a always on connection so don't worry about it if you don't want. I asked about other computers or wireless networks possibly connecting directly to our wireless computers shared folders via the wireless cards and he told me that WEP would cover that from all but determined hackers with some time. OK well, work and school don't have WEP enabled on their Wireless networks (school is understandable-public acess, my work is just ignorant but they don't really have anything shared on the network anyway)...... my friend didn't really have an answer for that. He said the internet access should be fine, it is firewalled, but our shared folders my be vulnerable to a prankster on campus with no WEP enabled. Work is not much of a concern as the wireless network dose not extend outside the building. So.... Is all this true?
