Access the Internet from an XP Machine on the internal Network

[Techstyle]

I have a ADSL modem/router connected to the LMCE core Eth0, LMCE Core Eth1 connected to a Linksys router, XP Laptop connected to the Linksys Router.

From the core I can access the internet.

From the Laptop I can access the Adsl router setup page.  Skype also works but I cannot load a page using internet explorer.  Is there something I am doing wrong?  I am not trying to use a Proxy Server.

Thanks in advance for any help

You need to supply some basic troubleshooting data before anyone can help you.

First - why are you using a router for your internal network? Get a hub or a switch. At least make absolutely sure you are only using the LAN ports and not the WAN port.

From the XP command line run:
ipconfig /all
ping google.com
tracert google.com

This should tell us how the XP machine is connected to your internal network, whether it can route outside its local subnet, whether it can do DNS resolutions,etc...

Oh, one other thing - I assume you have told your ADSL router how to find your internal subnet?? If not, how is it going to know that subnet even exists, much less how to get there?

Generally, you need to add a static route to your ADSL router telling it that the 192.168.1.0/24 subnet is routed via whatever your core's external IP address is...

I am using a router because it has a WIFI connection for my PDA orbiters and it was available.  nothing is connected to the WAN port.  the Laptop and core are both connected to the 4 LAN ports.  it is only this laptop that does not attach to the internet I now believe (this I think is my configuration rather than an LMCE problem)

Let me get this straight, the only actual problem here is m$ internet exploder?? 

[Techstyle]

Good question,

Skype seems to work - I can make the test call

I can access the ADSL modem/router that is the internet gateway and log into it

I cannot access the internet using MS internet explorer, I just downloaded Monzilla and that also cannot access the internet.

I do not get any response when pinping google.com

this laptop was tried unsuccessfully as a MD.  Looking at the IP address 192.168.80.5, shouldn't the IP address be higher than this for a non LMCE device?

my settings say 192.168.80.2 - 80.128 for pluto devices.  80.129 - 80.254 for anonymous devices

Don't think I can fix this for you just yet, so just comments initially:

Yes, it clearly was used as an MD at some point from the IP address. The core's DHCP server recognises the MAC address and so handed out the same IP.... is this a problem? I wouldn't have thought so, maybe Zaerc can comment on that.. I have got something at the back of my mind ringing bells.... perhaps you should delete the MD and you will probably have to remove the reservation and MAC address from the DHCP config file as well. Get it back into the right range.

It can't connect to anything because it can't resolve names. Now try:

ping 101.1.0.53 and 54 and try tracert'ing them as well - you have to have access to your DNS servers.

The other thing is, your node type is mixed, this is extremely unusual - it should be hybrid. But this only effects NetBIOS name resolution, so I don't think that could be it...

Start with the ping and tracert to your DNS servers from that machine and from the others... if you fix that, it should fix the problem...

As the MAC addresses are different for different adapters I tried using the WIFI adapter instead of the wired adapter and can now access the internet. with this in mind I would like to try removing the wired ethernet device from the DHCP config file but I am not sure how to do this.

Can anybody give me instructions on how to edit the DHCP config file?

Thanks
