can't use browser beyond subnet

[PSLog]

Hi

Win2K Pro.

I'm using a Nokia M1122 router to provide access from my local subnet to the internet.

I can ping each node on my subnet and the router and I can ping outside the subnet ie beyond the router.

Using either IE or Mozilla I can connect to the router admin page, but nothing beyond it.

That is - I can ping beyond my router, but can't access any URL beyond my router using a browser.

What are the next things I can test?

You need to set up the WAN part of your router, with the IP-address and DNS-servers your ISP has given you.
In the LAN part of your router you either activate DHCP to give local IP-addresses to your clients (PC's) and set your PC's to automatically obtain IP and DNS (in your network-settings), or
you disable DHCP and use the fixed IP-addresses of your current setup.

If you need more info, tell us how your network is currently set up.

Well done realblackstuff,

The WAN interface is not set up correctly with the settings for the ISP.

 

[RealBlackStuff]

Much appreciated, Phantasm66

Oops!
I omitted to explain the following:
Sub-net comprises computers A, B and C
The browers work perfectly (accessing internet sites) from A and B but not C. Yet I CAN ping internet sites from C.
(Sorry - that was a fundamental omission!)
This suggests the router set-up is OK - but that something on C is not set-up correctly?

 

[Phantasm66]

So, what you are saying is that you are getting most internet access on C, but not http??

Can you ftp, use smtp or any other internet protocols - is the problem specifically with http and therefore web browsing?

try to ftp to an ftp server from the command prompt.

if you can use other internet protocols, and not http, it suggests that the browser program itself may be the problem. And, course, could be any firewalling software such as zonealarm, which you should disable. Try looking in the connection settings section of the browser and remove any proxy servers, etc.

Can you tell me how to check access to ftp please?

I have 3 browsers on C and cannot access any http site with any of them.

Thanks

Here's an ftp near where you are:

ftp.wicks.co.nz

Do this:

Start, run, cmd, return.

Opens command prompt.

Type this

ftp ftp.wicks.co.nz

Use username anonymous and enter something like an e-mail address for the password.

Then, once connected, try to move in the directory structure, ls or dir to list.

If this works, you have ftp access. That means that the problem with web browsing is http related, as opposed to being a problem with network connectivity or configuration itself.

 

[PSLog]

OK
It said
c:\>ftp ftp.wicks.co.nz
Unknown host ftp.wicks.co.nz.
ftp>
What does that tell us?

PS I WAS able to execute the above from another computer.

 

[Phantasm66]

what happens if you say

ping ftp.wicks.co.nz

?

 

[PSLog]

Ping ftp.wicks.co.nz
Unknown host ftp.wicks.co.nz

Ping (a known external IP address) = OK

 

[RealBlackStuff]

Check the security settings on that C-computer
Right-click Internet Explorer on your desktop and select properties, then the tab Security.
If it is too high, you can't access anything.

 

[PSLog]

The security level is set at medium.
Note that ftp is not working either, but ping works both by name and IP address.

This was all working before I upgraded windows from NT4 to Win2k.

 

[Phantasm66]

so you can ping an ftp server from the machine, but not connect to it? Then surely its your firewall rules that are wrong?

 

[RealBlackStuff]

Is there any NWlink/IPX driver installed?
If so, remove them if you are not connecting to any Netware stuff.

You should try accessing something via IP address, not hostname. Do a "ping 12.96.164.87" or in a browser http://12.96.164.87 (It's TechSpot). If you can connect to an IP address, then you have misconfigured DNS in the TCP/IP settings.

You beauty! (Kiwi slang: not to be taken offence at)

Thank you very much

 

[Phantasm66]

Was that it? If so, great!

 

[PSLog]

Yep. That was it.
Sorry, one answer I gave you was wrong, which caused a distraction.

Thank you for your help too.

 

[Phantasm66]

What action have you taken to resolve the matter (answering these questions is good for the next person who does a google search and finds this thread - let's not forget about them!)

 

[PSLog]

Good point.

I found that in the Control Panel>Network and Dialup Connections>Local Area Connections>Properties>TCP-IP>Properties (breath) the Use the following DNS server adresses section was empty.

I entered the DNS addresses that were in the other computer and hey presto - it worked.

This is a very useful forum - thanks

 

[Phantasm66]

Yes, that would be a first port of call. I should really have mentioned it from the outset - to look at the TCP/IP settings and see that they match.

Sometimes, I think that the forums are as much about some people sharpening their troubleshooting techniques as it is about helping people or being helped. I come here not to really ask questions but to improve on the quality of the answers I give. I think many others post here for those reasons as well.
