Connecting the world…

Blog offline.. and online again

This blog was offline for a couple of days, because my ISP thought it would be cool to change the public IP address.

I bought a house with my girl and we are still rebuilding the place. However the end is near. I already signed up with an ISP, which is XS4ALL. It is always a difficult choice when choosing a new provider, but this one offered my a free Wii, so the choice was very easy. But because I am still rebuilding I haven’t been able to connect my router, so the Synology NAS with this web server is still running at my girls parents.

They had Orange as ISP, but Orange now merged with Online. And Online thought, lets change the public IP address of all the modems. At the moment I am in an hotel in the northern part of the Netherlands for 5 days. A friend told me, he couldn’t browse to the blog, so I thought there was a minor problem with the internet connection at home. After doing some research I noticed that the public IP had changed (I could have found the problem sooner if I had used something like DynDNS….).

So I thought, lets just change the NAT mappings in the router, but paranoia as I am, I configured a very strict ACL on the router, so I couldn’t remotely log in to it. Finally after some help from home, I managed to get into the router, change the NAT mappings and ACL statements and change the public DNS records. And see here, the blog is online again.

I hope Online doesn’t do the same trick again in the near future……..
