Internal ping works, but external does not

Babs · 04-25-2005, 12:50 PM

Hello!

I'm not quite sure the right questions to ask, so I'll explain the problem as best I can and hopefully someone can point me in the right direction.

I've got a static IP address (I think) that resolves to samaritan.homeip.net which, from inside my network I can ping just fine, but if I try to access it through a web-browser, I get request timed out errors. I can get to the internet from the machine I'm trying to access, but I can't get from the internet to that machine.

I used to be able to access this machine just fine until today when the network card went khaput and I replaced it. I'm really new to this stuff, so I appologize if I haven't provided enough information. Please let me know what else I need to determine in order to resolve this issue.

Thanks so much!

Did you replace the ip information after you installed your new card? If you didn't it's likely you got a new ip address assigned to your computer through the DHCP which is usually the default. You just need to put in the old ip information and you should be fine.

Start, Run, type cmd, type ipconfig /all.

Post info.

Do you know what the previous IP config was?
IP address
Subnet mask
Default gateway

DNS servers

It appears that the ip address had been changed when I installed the new card. I changed it back to the original and it works just fine now. Thanks so much for your help.

Can you recommend a good book/web-site where one could learn about networks/masking/port forwarding, etc?

Thanks again!

Port forwarding is rather easy. You just look at your Router manual.

Do you want to learn about Subnet masking. Learn To Subnet is pretty darn cool.

If you want to learn networking may I suggest taking a few classes at a Tech College.

If you just want the subnets calculated for you, try the Solar Winds Subnet Calculator, free.
