What happened? Can you try restarting the Webconfig from the console "service webconfig restart"?

Can you ping the gateway? Can you ping 8.8.8.8 as well?

Please can you install PuTTy and WinSCP on a PC and see if you can get them to connect to ClearOS. (WinSCP with SFTP protocol on port 22, PuTTy also on port 22)

the 192.168.2.254 is the gateway
The link did not work

So the ClearOS LAN IP is 192.168.2.254? Please can you confirm this? If so the DHCP server is working. Are you using https and not http and port 81 when trying to connect to the webconfig? Try clicking on this link. Does it take you to the webconfig?

I do know I can ping the ip address of the server, but when windows checks for the name \\alanizdc\ its says its doesn't find it.
On the server the names with external is alnanizdc
From my computer I use to be able to type in the IP address with a :81 and log into Clear OS, can't do that anymore.

Let me know if i'm putting to much info out here, that may also open up my server to attack?

Well hope this isn't too dangerous posting this info. anyhow i typed in at the command prompt ipconfig /all and this is what I got back.

"ipconfig" is a command that you would run from a command prompt on a PC. I'd like to see what appears on screen when you run it.

What is the ClearOS LAN IP (from the console)?

PuTTy is a (free) program you can run on a PC to create an ssh session on the PC to connect to ClearOS. Similarly WinSCP is a (free) graphical file manager you can run from a PC to browse the files on ClearOS, however both programs rely on you being able to make a connection to ClearOS.

Sorry pretty green to all this. But just for clarification, I don't see the original ip address on my pc, is see that setting on the server.

when I go to the server and log in, it shows as ClearOS Enterprise Version 5.2

As for what the ipconfig out put is ???
Not sure what ssh into server means or putty

I don't like it that you still see the correct LAN address. On your PC, what is the output of "ipconfig" for your LAN adaptor or even "ipconfig /all" (just for the LAN adaptor).

Can you ssh into the server (perhaps with PuTTy)?

I also am wondering if the firewall has gone into panic mode, but I think that leaves the webconfig working.

Please can you confirm if you are on ClearOS 6.x or 5.x?

Thanks for the help, well I can go to the server and log in, and there is a External, (the one I changed) and a LAN one that i did not change. But still nothing? i do know what they were before but it is the old IP address from the other ISP.

Possibly the best thing to do at this point is to log directly onto the ClearOS console. From there you can get to the basic network settings and change them if needed. Do you know what they were before you made the change? Do you know which interface in ClearOS is the LAN inerface and which is the WAN interface?

For your ISP you should only have been changing the WAN/External interface settings. The LAN settings should have remained unchanged.

Which IP address were you using to access ClearOS? (If it is a LAN IP address it should be safe to publish).

Check, but it sounds to me like (assuming there are 2 network cards) you may have changed the address on the wrong card.
