A firewall sits between your computer and the internet.  it blocks unwanted connections from hackers.

The firewall blocks packet 'attacks' or port attacks/intrustions from people in the internet. \n\nanti-virsu programs protect malicious programs already on your computer from doing bad things, or try to reverse damage done by them, as well as deleting the bad programs.

There is a saying that goes "prevention is better than cure". A firewall in layman terms is essentially a program wich filters network data to decide whether or not to forward them to their destination or to deny it. Well, getting to the point there are good free firewalls, such as:\n-sygate\n-zone alarm\n-xp\nsome other are also very good but are not for free, but you can make the download with emule:\n-Black Ice defender\n-Lockdown 2000\nok?

I don't have any experience with that server, but I use windows, and if I hold down the "ctrl" key, it will override\nthe firewall. Give it a try, you have nothing to loose..good luck..

A firewall is a protection system for your computer that protects it from unsolicited communication when you are on a network.\nIf you use a good firewall then it will not only suspicious incoming traffic in the form of viruses,trojans,worms,spyware etc but also outgoing traffic.\nWhen you already have some virus in your computer and the virus wants to spread itself using  your internet connection then a firewall will prevent even that.\nThese days its a must to use a firewall as virus activity is growing.also use the Y! toolbar's spyware removal tool.It is very good for removing spayware that are not caught by your firewall.

The word proxy means "to act on behalf of another," and a proxy server acts on behalf of the client and the server. All requests from the clients to the Internet go to the proxy server first. The proxy evaluates them, and if allowed, re-establishes the requests on the outbound side to the Internet. Likewise, responses or initial requests coming from the Internet go to the proxy server to be evaluated. The proxy then talks to the client. Both client and server think they are communicating with one another, but, in fact, are dealing only with the proxy.\n\nWhereas a firewall is a piece of hardware and/or software which functions in a networked environment to prevent some communications forbidden by the security policy.

What Firewall setup are you using?

A firewall protects your computer from internet threats. Such programs might be blocking Limeware or other internet program from accessing the web. If Limeware connects then there is no problem, if it does not then you'll have either to disable your firewall or unblock Limeware in the firewall settings.\n\nCheck Limeware help files for more info.

for one if your using a windows pc the firewall supplied is junk. i could hack tht with my dog at the keyboard. get you self a better reputed fire wall like one by symantics. or which ever one you choose. install it an then it should ask you everytime you accses a program tht connect via internet. if you know the program is safe enable it to accese. if you are worried it is nopt then dont let it use the net.

Zone Alarm.\n\nThis is the best Firewall from my experience, nothing gets through.\n\nThe only problem is it blocks EVERYTHING, you have to allow certain processes to have access not only to the internet but also to the privileged zone.
