Router   v/s   Firewalls .?

A device that forwards data packets along networks. A router is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISP’s network. Routers are located at gateways, the places where two or more networks connect.\n\nRouters use headers and forwarding tables to determine the best path for forwarding the packets, and they use protocols such as ICMP to communicate with each other and configure the best route between any two hosts.\n\nVery little filtering of data is done through routers. \n\nA system designed to prevent unauthorized access to or from a private network. Firewalls can be implemented in both hardware and software, or a combination of both. Firewalls are frequently used to prevent unauthorized Internet users from accessing private networks connected to the Internet, especially intranets. All messages entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria.\n\nThere are several types of firewall techniques:\n# Packet filter: Looks at each packet entering or leaving the network and accepts or rejects it based on user-defined rules. Packet filtering is fairly effective and transparent to users, but it is difficult to configure. In addition, it is susceptible to IP spoofing.\n# Application gateway: Applies security mechanisms to specific applications, such as FTP and Telnet servers. This is very effective, but can impose a performance degradation.\n# Circuit-level gateway: Applies security mechanisms when a TCP or UDP connection is established. Once the connection has been made, packets can flow between the hosts without further checking.\n# Proxy server: Intercepts all messages entering and leaving the network. The proxy server effectively hides the true network addresses.\n\nIn practice, many firewalls use two or more of these techniques in concert.\n\nA firewall is considered a first line of defense in protecting private information. For greater security, data can be encrypted.\n\nI have a router and a firewall.  A combination of both will provide the best security.  The more layers an attacker has to get through, the less likely he will try.  I have a D-Link router and I use ZoneAlarm as my firewall.

You have to learn how to get into the setup for your router.  It usually involves going to a specific URL while in a web browser.\nLearn a little at a time about your system's security set-up.  In the end, you want to set up a PSK (pre-shared key), change the default URL so even if someone breaks in, they won't find the setup, turn on the firewall, and turn off ping response.

there are 2 kinds of firewalls\n\n1. hardware firewall - Buy a router that acts as a firewall\n2. software firewall - dowload programs that are software firewalls. basically they hide your computers ports and prevent people from accessing your comm ports. you can get a software firewall at www.zonealarm.com

It may not be a firewall problem.Try unticking the "use proxy server box" and tick on the "automatically detect settings box" (in Tools/Internet Options/Connections-Lan Settings). It worked for me.

Norton is better than Windows firewall.I suggest ZoneAlarm and they have a free version that works great.I have had it for 5 years and never had any problems.You can download it free from the site below.

Use a hardware firewall with NAT and all ports stealthed. Make sure UPnP is disabled, and only allow outgoing connections to trusted (non-proxy) sites.

Your firewall may be preventing access to the DSL connection. Norton does this at first, same thing happened with me, it sorted itself out after a few days, I wouldnt worrie about it too much. \n\nI wouldnt use the trail of Norton Internet, pointless. Either download a full verion of www.waushare.com but the servers down...\n\nIf you firewall is preventing access then go into controll panell and go on to to firewall, turn it off see if that helps.\n\nIts Norton thats your problem, but its okay nothing to worrie about :)\n\nLuca

My personal favorite is Zonelabs ZoneAlarm Pro.. but just get the firewall pro.. they have different versions that come with antivirus and antispyware programs... but just the Firewall is all you really want from them.

get rid of zone alarm, the only place you need a firewall is where your network goes out to the internet, so if you set that up correctly, you shouldn't have any problems with your internal network.    If you don't have a firewall going out of your network, then you are at risk and should go buy a router with a firewall.
