To change my fixed IP (from A to B) for my domain. RRS feed

  • Question

  • Hi,

    I used an Acer H340 before and located my personal fixed IP 123.123.123.123 (for example only) to c01029.homeserver.com. Because of changing service provider, my fixed IP was changed to 456.456.456.456 already. How could I change the mapping now? (To locate 456.456.456.456 to c01029.homeserver.com)

    Thanks for your feedbacks.

    Regards, c01029.

  • You shouldn't need to do anything as it should just happen automatically. Your xxx.homeserver.com should use DNS to reference whatever your external IP is, allocated by your ISP. If you do not have a fixed internal IP address, you may need to change Port Forwarding in your router.

  • Thank you Phil.

    1 thing I forgot to highlight is my H340 was crashed and I guess nothing is doing updating my fixed IP for XXXX.homeserver.com. That's why I'm asking for manual change. Is this possible?

    Moreover, I already did "ping c01029.homeserver.com" and make sure it's still mapped to previous fixed IP (123.123.123.123), not my current new fixed IP (456.456.456.456).

    Regards,

    c01029.

  • Is 220.135.142.194 (response to Ping c01029.homeserver.com) your current IP address or your old one?

  • 220.135.142.194 is old one. My new one is 114.32.28.102.

  • So it's not updating for some reason. There is a Ping response to your new IP address but no response to https://114.32.28.102/ - have you got your Port Forwarding set up correctly?

  • I think so. I set up FTP, IPCAM, ...,etc., before. I did NAT setting in my router. Is there any special port to be enable for auto-update?

    For NAT : I enabled 80,443,3389 & 4125 before. And also for other applications.

  • No, you just need 80 & 443 for remote access. I can ping your IP but not see your Server so there is something else wrong. Try www.grc.com and use ShieldsUp to see if those Ports are open.

  • I checked my FTP, IPCAM, ...,etc., ports and found it works. For port 80, I opened the port but didn't set any service from my server. Also, I checked GRC and got the following comments. I thought I did open some ports. Could you advise which ports are related to IP update for DNS server?

  • What results do you get if you run ShieldsUp on all your Ports?

    This may help regarding other Ports, but normally you only have to forward 80 & 443 to your server:

  • I just found where to test it. Sorry.

    After testing, the results show most of the ports are stealth (green) including 80 and 443. It's strange to me. My NAT router doesn't change anything and the domain name worked well till changing the new IP.

    Does it mean there is something blocked from my ISP? Is there still anything I could do to solve it?

  • It could be your ISP blocking but equally it might be your router. What does Remote Web Access show in the WHS Dashboard? If it says it's not available, try manually forwarding Ports 80 & 443 to your fixed Internal Server IP and try ShieldsUp again to see if they are actually open.
