Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I have a windows server 2008 machine that I use for IIS. I usually host all my sites on one IP address, my main IP. However, I needed to host a site with SSL, so I created a new site in IIS manager binded to a previously unused IP address.

However, I just cannot manage to access the site from any other computer. The site works fine if I access it from the browser on the server, but it just won't work if I try to access it from any other computer. I tried pinging the IP address, but it does not respond.

any ideas? thanks

edit: the ipconfig:

I used to host the sites on 176.61.136.104, and now I want to host one on 176.61.136.105, but it seems like I cannot ping 176.61.136.105 (but pinging 176.61.136.104 does work). However, I can ping both on the server.

Did you just randomly pick some IP address, or was this IP address assigned to your computer but not used? –  DerfK Jul 13 '12 at 12:46
    
it is assigned to the computer, and I can successfully see it in ipconfig. I can also access the site if I visit the ip address on the server's browser –  Sihan Zheng Jul 13 '12 at 12:48
    
Please tell us more about your environment. Also post an ipconfig /all of that server –  MichelZ Jul 13 '12 at 13:20
    
I added it, plus some more description regarding the error. thanks! –  Sihan Zheng Jul 13 '12 at 13:26

You can ping and access the site locally on the server but not from another machine and this is a web server which means it is likely sitting behind a firewall.
1) Have you confirmed the firewall rules allow the connection?
2) Have you tried ping/http from another machine on the same subnet?
3) Is there a host-based firewall on the server that needs to be configured to allow access to the new IP?

Thanks, it was a firewall problem –  Sihan Zheng Jul 13 '12 at 21:40
