Clouds are even cheaper 2. Answer-continuation
Having played enough with DigitalOcean, using the information in the article “Clouds are even cheaper” , first of all I want to thank tangro for the quality material and share my experience with the community.
So, let's say that we have an image and droplet on DigitalOcean.
Add a script to the download that will update the IP address in the PPTP and iptables settings file.
Next, make the script an executable file and add it to the autoload:
')
There is a lot of extra code, and the method is probably not the best. But it works.
Do not forget to update the image!
Advanced PPTP settings for Ubuntu
We put NodeJS and clone this repository to us.
In the file config.json we write the name droplet, the name of the image and your API key (take here ).
Thereafter:
This “hand-made article” will create a droplet with the specified name from the specified image, asking the region and size from the list of available regions for this image.
In the new regions, I'm sorry, you will have to transfer the image yourself. It's up to you to decide.
If a droplet with the same name exists, it will be deleted.
After the script deletes the droplet, it most likely will not write anything.
After creating droplet, the script will display the IP address of the new droplet.
Droplet will start working normally (approximately) 2 minutes after the script ends.
This script can automatically manage any droplet created from any image, there is no binding exactly to PPTP.

Solving possible problems when configuring PPTP on a router
Router
Delete all lines in / etc / ppp / pptpd-options except:
And update the image, so you do not wonder why the settings are not saved.
In the settings of the router, select "PPTP / Russia-PPTP" (all manufacturers write a little in their own way).
ms-dns 8.8.8.8 ms-dns 8.8.4.4 And update the image, so you do not wonder why the settings are not saved.
In the settings of the router, select "PPTP / Russia-PPTP" (all manufacturers write a little in their own way).
