    Thank you. But none of above method works after I tried to telnet the ports 22,80, or 21. Is there any policy blocks this. My PC is in the safe subnet of firewall. However, I don't have any management/monitoring permission. I only have their IP address.

If you know the IP address then you have two choices:
Indirect method: Test a 'listening' port on the firewall. For instance, if there is a web server behind the firewall, check HTTP (TCP/80) or FTP (TCP/21).

Direct method: If it is enabled for remote management you can check the remote management port, typically SSH (TCP&UDP/22).

If you've never done port level testing there are a number of ways to do that. Microsoft provides a commandline tool named portqry: http://www.microsoft.com/downloads/details.aspx?familyid=89811747-C74B-4638-A2D5-AC828BDC6983&displaylang=en

As well as a gui interface for it: http://download.microsoft.com/download/3/f/4/3f4c6a54-65f0-4164-bdec-a3411ba24d3a/portqryui.exe

    Are you now able to monitor the firewall?

    Which method did you use?



    I forgot to mention using SNMP queries, but it sounded like you were looking for a less direct method of identifying the firewall status.

    It sounds like your only option is passive monitoring, which means you must know what is allowed to pass through the firewall and test communicating with the 'allowed' device. It helps to have more than one to test against, since the firewall could be 'up' and a single device could be offline. That's where the port tests mentioned above will come in handy.

    For instance, if a web server is allowed passage, you could check port 80/TCP against it's IP (not the IP of the firewall).

    Do you have any insight into what is allowed through? It helps to know both outbound and inbound allowed activity. In some rare instances a firewall is established with no allowed activity, waiting for that first request. Maybe you could request passage for a couple of devices outside your firewalled area and use them to test against.

    Good Luck!

open the command prompt and type ipconfig, the default gateway is the address you need to log into in the browser. Keep in mind ICMP pings may be blocked by firewalls.

Rrouter is not transmiting to other computor


This is quite a long reply and may appear very technical - however, have a read through and see what you can do Answer.The following assums that your wireless connection is working and other PCs are able to connect:
There could be quite a lot of reasons you are not getting a connection to the wireless - some common issues
  1. the wireless is switched off
  2. Firewall may be blocking
  3. Security code entered incorrectly or old profile
  4. the DNS is not working
  5. Something else on the PC blocking
so quite a few things to check - so lets start in order
  1. Wireless Switch:- Most laptops have a wireless switch - some use a physical switch, other use a combination of the FN key + one of the F keys to toggle on/off - make sure this is on
  2. Firewall:- The firewall my be blocking access - try to disable the firewall. Often programs like Norton, Mcafee etc, when the subscription runs out can cause issues and need to be uninstalled, to uninstal you may need to use the removal tool available on thier websites. One of the ways to test this, is to do a PING test. Press the "Windows key" {bottom left of the keyboard} and at the same time press the "R key", now in the search box that appears - type "CMD", a black box will now appear on your screen, in that box type the following "ping google.com" if you get 4 replies then you can access the internet and your firewall may well be blocking the access try disabling the firewall.
  3. Wireless Security:- Loginto the router, this may seem difficult, but its really straight forward, - however you will need to know how to login into your make of Router - A manual will be available from the routers manufacturers website to explain how to login. Once you have logged into the router main page, goto the wireless section and remove any wireless security, this maybe a simply as a box and click disable. --- Now see if the machine will connect to the wireless.
  4. DNS issue:- This may appear that you are not connected to the Internet, but in fact you are but cannot use names like google.com or bbc.co.uk. To test this you will need to ping a website name and then ping the website number. If you get a reply from the number, but not from the name, then its most likely a DNS issue. The test is as follows Press the "Windows key" {bottom left of the keyboard} and at the same time press the "R key", now in the search box that appears - type "CMD", a black box will now appear on your screen, in that box type the following "ping google.com". If you get a reply then its NOT a DNS issue however, if you get no reply then type the following "ping 209.191.93.53". if this replies and the name did not then you most likely have a DNS issue. To temporally fix this issue, you can use a public DNS set of IPs on your PC - goto this site http://code.google.com/speed/public-dns/ and use the google dns public address. There is a configuration link on that page, which explains how to setup. If your PC is now working and can connect to the internet - post back a comment and we can try and resolve whats really causing the issue.
  5. safemode:- Try to boot the PC into "safe mode with networking". To do this switch the PC on and now as it starts keep tapping the F8 key untill a menu appears, from that menu choose "safe mode with networking". If you can now connect to the internet,then there is something blocking your access on the PC when it starts normally - post back a comment and if that's the case, We can try doing a "clean boot" and try to identify the startup or process that is causing the issue
A very useful tool to use for wireless issues is xirrus, http://www.xirrus.com/library/wifitools.php If you can copy the program onto the PC thats not working and install and run, this test if your adapter is working and also will display all the networks broadcasting in your area. Which will prove the hardware works.

4. Go to the privacy tab click also on the default button

There are websites that are blocked and I want to know how I can unblock them without getting in trouble.


in the school right!?
use online services like http://anonym.to/
or try to access the website by it's ip address, not the name.
Some firewalls just block the url, not the ip ;)
to get the ip, simply ping the website like:
C:\>ping www.facebook.com
A fazer ping para www.facebook.com [69.63.181.12] com 32 bytes de dados:
Resposta de 69.63.181.12: bytes=32 tempo=205ms TTL=244
Resposta de 69.63.181.12: bytes=32 tempo=207ms TTL=244

And then enter http://69.63.181.12
in you browser

Cannot connect to 192.168.1.1


You must check if your PC is getting correct IP from your router by running ipconfig on DOS command. The Default Gateway must shows 192.168.1.1. Just to be sure this IP is accessible, run a ping test (Ping 198.168.1.1).

C:\Users\PC>ping 10.1.1.1

Pinging 10.1.1.1 with 32 bytes of data:
Reply from 192.168.1.1: bytes=32 time<1ms TTL=64
Reply from 192.168.1.1: bytes=32 time<1ms TTL=64
Reply from 192.168.1.1: bytes=32 time<1ms TTL=64
Reply from 192.168.1.1: bytes=32 time<1ms TTL=64

Ping statistics for 10.1.1.1:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms

C:\Users\PC>

You will see the above results if the test is successful. If it failed, possible a Firewall is blocking the PC to access the Router. Try to disable it and see if it will works. If the same issue or even the test passed but can't access the IP address, reset the router to factory defaults by pressing the small hole at the back of the router. Then do the above steps again to see if you can now access it. Hope this helps.

Nokia IP380 configuration for MQ Gateway


The Nokia IP 380 runs the CheckPoint Firewall software. A quick look on the checkpoint site should get you a user guide that would work.

Checkpoint Software

Try that link.

Also, if you're referring to MQ Series or the new IBM Websphere MQ product, that runs on port 1414 by default.

Please rate me if I solve your problem.
