Dose this router work as a firewall switch?

Hi There,
I need configure this router as a firewall switch for an industry control computer. Ideally, i need close all ports except one for sending out email, and 4 other ports for remote access from internet. Is this the right router?
If it is, I also need confirm the following issue.
1. I need make port forward for all these 5 ports on the router. My understand is port forward = open port. correct?
2. How can i close all other ports?

Thank you very much.

It is not possible to close all the ports on the router.
you can open other ports.
by default port 80 is open on the router.
On the router there is no such setting to close the port.

I am trying to games on PS3 and cannot connect with friends. I believe this is because I have NAT Type 3 (closed) and I would like to change it to NAT Type 2 (moderate) but I do not know how.


Hi ..

The PS3 has 3 different NAT types. They are shown below.
Type 1: The PS3 is connected to the Internet without a firewall or router. No NAT issues.Type 2: The PS3 is connected to the Internet through a router which is configured correctly. No NAT issues.Type 3: The PS3 is connected to the Internet through a router that needs configuring.Ideally, you want to have a Type 2 NAT. However, a Type 1 NAT does not affect your game play.


First of all you will have to Disable the firewall in the Router / Modem

If you are using a Router ..

Then

Make sure that UPnP(Universal Plug n Play) is enabled
Enable the IP Address of the PS3 in DMZ

Or Forward the ports

Below are the TCP and UDP ports that need to be forwarded:

TCP: 80, 443, 5223
UDP: 5223, 3478, 3479, 3658

For more details on port forwarding , log on to http://portforward.com/english/routers/port_forwarding/routerindex.htm

Hope it helps

Regards

I cant get past the routers firewall for certain programs. How do I allow these exceptions? Help!


Your computer has the firewall installed in it, you will need to turn off or configure your firewall settings in your computer, to do that if using windows XP: Start/Control Panel/Switch to classic view/Windows Firewall, turn off firewall.
Windows Vista/7 Start/Control Panel/Windows Firewall turn off firewall. Follow these steps good luck.

Need network key, wireless is not working it logs me off all the


1) Your Network or DSL router may have bad or missing information. Powercycle your router and/or rebuild the configuration in your router.

2) Double-check your cabling to the computer. Make sure you have the correct type of cabling, straight-through CAT 5 or possibly a crossover cable and try another cable or test the cable to make sure its working properly.

3) Check your network card to make sure its configured correctly and working properly. Many times setting the network card to 10Mbps/Full Duplex will solve this issue. To do this, open Control Panel, System, Device Manager. Go to the properties of the Network card, click on the Advanced tab and find the Link Speed and Duplex section. Change it from Auto Detect to 10Mbps/Full Duplex.

4) Check and test your firewall. Your firewall, especially if its a software firewall like ZoneAlarm, Black Ice, Norton Firewall or something else could be blocking the connection. Disable your firewall and test the connection. You may have to resolve the problem by even uninstalling and reinstalling the firewall.

5) Check your IP address assignments and workgroup settings in the computer for accuracy. Statically assign IPs to the computers in your network.

6) Reset your TCP/IP stack by downloading and running WinsockXPFix.exe a Visual Basic program designed to fix corrupted TCP/IP issues, host file problems and a variety of other connectivity issues.

7) Also this issue is relate to SP2 update (in that case you should run the Microsoft patch (KB884020) for it.)

Belkin Wireless Router F5D82314 worked fine for a year, now will not allow desktop or laptop to go to links from homepage


Hi!

Can you describe your setup in a little more detail, please? What OS's are on your computers, what firewall and Anti-virus programs are on the computers, and especially did you change anything else at about the same time that this problem started?

The easiest way to determine if a firewall is the problem is to turn the firewall completely off and see if the problem goes away. If it does, you then know that you need to configure that firewall so that it will work properly in your environment. If I were to venture a guess (which could be totally wrong), a firewall on your computers (like one that is installed as part of a Norton/Symantec program, for example, even if the program isn't labeled as a firewall) is in conflict with the router's firewall.

Please let me know if this helps and good luck!

Switches need to configuration. For a hundred PCs you can get away with settingthe DHCP pool for it, although ideally you want to set up multiple subnets.
