Ask Me Help Desk - Firewall will not permit 2nd house computer with router

Firewall will not permit 2nd house computer with router

I have a computer in another room, linked to the main computer with a wireless router. I have no idea how to tell the firewall about this particular computer, and distinguish it from a possible hacker computer. I get many messages, but I cannot tell one IP address from another... I do not understand most of the messages.

I had my daughter send me a message to my personal website to see what her IP address is... it is the same as mine... but I do not see her on the firewall list..

I am confused as to all the terminology which pops up without any real explanation... I just block everything I do not understand.

I go this firewall because I thought someone was hacking into mine, and I do not want to accidentally allow a bad link... trying to connect my daughter.

How do I connect the 2nd computer on the home network to my computer? :confused:

The address you see from outside is your modem's address. The router takes that address and assigns private addresses to your PCs, usually in the 192.168.x.x range. To find out your IP, you need to get to a Command prompt and type IPCONFIG /all.

What makes you think it's the firewall? What messages do you get?

Where do I go to get a command prompt?

All this started when I installed COMODO... firewall... the thing does NOT come with real instructions for the non-IT user.

I know my IP address, because I can go to...
What Is My IP Address? - Lookup IP Address Location (Trace IP/Track IP)
And it automatically shows me my address.

I also have a private website and when people leave comments, I can see their IP address. I told my daughter to make a comment to see what hers was... so I know both IP addresses.

I do not know how to tell the firewall to let my daughter access the internet via the router... her connection stopped when I installed the firewall.

That sites shows your PUBLIC IP, That's the one assigned to your router, NOT thde one assigned to your PC by the router.

To get to a command prompt go to Start and Run CMD.

I went to run... then typed in cmd... I just got a black screen. So now what?

Ok wait... I typed in what you said... it says, among other things... routing is disabled.

So what do I do?

What is a dns responder? I keep getting messages about that... I notice it says something about dns on the screen

Without seeing what it actually says I can't tell. But in there will be your IP address.

I don't know if the firewall is the problem. I'm not familiar with that firewall, but most firewalls are local meaning they control access to the PC they are installed on. That shouldn't affect other access to the router.

Ok... so what are the different things that would prevent the 2nd computer to connect via the router?

Is there a way on the black screen to enable the router? A command I can use?

The first thing to do is check if the other PC is connecting to the router. Does it get an IP from the router? Does the Network icon show a connection?

That is the whole problem... the other PC is not connected or it would be able to access the internet through the router.

Windows IP configuration says IP routing enabled... no

What do you mean by the network icon? How would the Firefox icon show a connection to another computer?

Firefox is a browser not the network. There is a network icon in the tray area that shows the connection. What version of Windows on both PCs? Did you run the Network wizard?

I have a local network, by using a wizard, with her computer.

Both use windows xp

In the tray area is an icon that looks like two PCs overlapping. That is your network icon. There may be multiple ones for wired and wireless connections. You need to check to see what the status of the connection on her PC is.

The internet is disconnected. It says disabled. Just like it did on the black screen.

So how do I enable her internet connection? She uses a router to my computer, and it was working until I installed the firewall.

Ok, What you should have is your broadband modem which connects to your router. Then each computer connects to the router either via an Ethernet cable or wirelessly (using WiFi). Try removing the existing wireless LAN connection on her PC from the Network icon in Control Panel. Then reboot and rerun the wizard.

OK... I did that and it is still blocked... it says disabled, firewalled on the icon. :confused:

How do I tell the firewall to allow my daughter's computer to have access to internet?

Thank you

You need to contact tech support for that firewall then or uninstall it. If its somehow blocking other PCs from the network, you have to configure it.

OK... there should be a way to tell the firewall what computers are allowed on the network... I have looked around on the menu and do not see anything helpful... I tried tech support forums, and no one has answered...

Last effort will be to uninstall firewall if all else fails.

Thanks

This situation is hopeless... there is no one to talk to about allowing a second computer on the firewall...

I checked her computer, and it does not have an IP address... according to...
IPCONFIG/all :(

Then uninstall that firewall

My daughter's computer is still disabled. It thinks the firewall is still present.

I'm sorry, but not being familiar with that firewall, I don't know how else to help. The only other thing I can think of is try going back to a restore point before you installed the firewall.

We will try that tomorrow, or I will while she is at work... I was sick of trying today.

Well, I tried. There is no firewall on my computer except what windows has... I should have realized I already had the one firewall, and not put the other on.

At one point, I tried adding what I thought was my daughter's IP address on the wireless network ( internet) connection, and then later realized maybe that was not her address, but the address for Yahoo. Once, I went to IPCONFIG/all, and she had no IP address, then later the next day, it was there... so I need to go back and find out what IP addresses are listed as OK... but I cannot find where I was... I have clicked on everything I can think of and that screen just does not come up.

It was a menu for adding IP addresses to the internet connection on my host computer... can you tell me where to look? Maybe this will fix the problem

My daughter still does not have internet via the router.

Is her computer wired or wireless? I agree with ScottGem in the fact that a software firewall should only restrict the PC which it is on. The router is the place at which I would begin. If the computer is wireless move it to the router and try it wired to see the results. Try bypassing the router to see if you can get an ip address from start-> run-> cmd-> ipconfig /all. The only way that I can think that a software firewall would affect the other computer is if ICS (Internet Connection Sharing) is turned on and used to manage the 2 pcs.

I am not sure I understand what you are saying. I am not too Tech oriented.

I have her IP address now. It just did not show up the other day when the second firewall was installed. Reason unknown.

Each computer ONLY has the windows firewall installed on its computer. The COMODO firewall is gone.

She cannot connect yet to the internet

She has a wireless router which used to work, until the 2nd firewall was installed. So the set up was correct.

So when I uninstalled it, the router should have worked again, but it doesn't.

How was the firewall uninstalled? I know that some firewalls require a special removal program otherwise it can corrupt something called your "tcp/ip stack". Also what is her IP address?

I went to "my programs" and did an uninstall.

Am I supposed to give out private IP addresses? :confused:

Private ip addresses are just that... private. It is assigned from your router so if you would like further help... a private ip address would be of help:)

This post is in a satirical mood. I am not being mean in any way:)

How can knowing my private IP address on the 2nd computer help? I am just being cautious...

I am also trying to locate where I list IP addresses as part of the network communications... I did it once, wrong maybe, and now I want to correct this... how do I find this spot on my computer? I have looked everywhere... I cannot remember where I went.

Depending upon the ip address it will show exactly how it is connecting or is not connecting. If it is a 192.168 then it is connected to the router or something else that has a dhcp client. If it is a 169.254 then the computer is self assigning an ip address. Please provide the ip address and xxx the last of the octet and it will allow me to continue troubleshooting.

IP 169.254.164.40

Mask 255.255.0.0

Ok... with a 169.254 address this is going to tell me that it is in fact not connecting to the router at all which is why you cannot get to the internet. A 169.254 is not a valid ip address. Are you able to directly connect this PC to the router for testing purposes?

The 2nd PC has a ton of stuff attached to it. It is in a different room. Not sure.

Like I said, the connection set up USED to work... now it doesn't

Is there any other way to test it without disconnecting all my daughter's stuff and bringing it into this room? She is not here. She is at work.

My modem is on the floor under the desk. It almost kills me to get under there. The belkin is on top of my desk, so that part is easier.

Well what security do you have on the router? WEP, WPA, wireless mac filtering? If you do not know this, then you may want to try resetting the router then re-setup the security for the router.

PS... The connection Used to say the 192 number, but when I saw that when the second firewall was up, I was sent alerts that drove me crazy. I thought it was someone hacking into the computer. I kept denying the request when the alert came up.

other changes I have made ( somewhere)
change IP address on my connections to the 169 number - I cannot find this spot and need help locating it, so I can change it back to the 192
computer name = daughter's name on both computers... confusion.:confused:

I have no clue.

What is WEP, WPA?

We have PCs, not a mac

Well MAC refers to mac address filtering not the operating system itself. If you login into your router (192.168.1.1 or 192.168.0.1) there should be a client list. If you need to contact belkin for support with that their number is 8002235546 options 2-2-6-3 and you will get a "live" representative.

How do I login to the router?

Go to 192.168.0.1 or 192.168.1.1 in a web browser on the main computer. I cannot tell you what the username and password are for that router because I do not use belkin routers myself.
