    I recently got another computer and networked. I have cable connection to the net. It's a wireless router with 64-bit encryption enabled. Do I still need, emphasize NEED, a software firewall? I don't want to wear two raincoats, but don't care to get wet either.

    Thanks for your help.

    Are you using the wireless? If you are and using WEP and NAT I would say dump the software firewall.

    Since I'm networking challenged (that's what IT is for at work, isn't it?) Could you please 'splain, Lucy, what WEP (encryption protocal?) and NAT refer to?

    I had to view your profile to see if you were old enough to understand the " 'splain, Lucy," thing. Nice bass.

    Yes, you should have a software firewall in all cases. The software firewall will control which programs on your PC can access the Internet which is something a router cannot do.

    I reckon I must be old enough to understand, but I still got no bloody idea. Must be a Merkin thing. :)

    You'd have to be on this side of the pond and have watched the "I Love Lucy" show with Ricky Ricardo and Lucille Ball to understand it.

    You absolutely have to have a firewall under any circumstance since you can conceptually control what goes in and out.If your router/wireless uses WPA,all the better..tougher than WEP.

    I suggest that if you do banking etc..that you turn the router off and use home base.

    WEP = Wireless Equivalent Privacy (or Windows Encryption Protocol, depending on who you ask) NAT = Network Address Translation

    Since I have Windows XP Service Pack 2 installed, I figure it wouldn't hurt to have two layers of firewall protection. As far as WEP, I used to have the 64 bit encryption enabled, but why encrypt? Encrypting, even though you can't really see the difference, slows down your bandwidth. When you consider distance between you and your access point, if you have a low signal, you might see a difference. For security, I have my router configured to allow only trusted MAC addresses on my wireless network - especially since I'm the only one that uses it. I could be wrong, but that's my two cents.

    I guess a super-hacker could see what I'm doing if they wanted, but I'm not as distrustful and paranoid as most. :)

    Regards,
    Tom

    Thanks, I'm distrustful, but not paranoid. At this point I'm 50/50 on installing a firewall, but am keeping one on the old computer since it's connected with CAT-5. It's close to the cable modem and that way I didn't have to buy another wireless adapter.

    Yes, this is very good.

    Some people are not worried about super hackers looking at network traffic, etc. because they don't have anything to hide. Well, the number one thing to worry about is someone using your wireless network to gain access to the Internet. Then if they are bad people they can access child porn or launch attacks on other Internet servers. Then, when the cyber police track this down, it will be your address where they'll show up for the arrests.

    Although, in the grand scheme of things, that's really quite paranoid.

    Thanks for all the input. I will be installing software firewall. After the initial confiuration and allow list, I really don't even know it's there unless I want notifications.

    Better paranoid than sorry.
