I woke up early on Nyepi and the internet stopped at around 7am. The night before I was reading about setting up a VPN:

It doesn't seem too difficult, but I couldn't be bothered in the end.
You also need to be able to forward ports as described in that article:

I looked quickly at the Indihome settings and this does seem
Take IndiHome, for example. Is the modem they provide a cheap and nasty affair, that gradually decreases in "performance" over time, to get people to upgrade to a more expensive service "package"? If you upgrade, do you get a "better" modem?
The modems seem fairly standard. I bought a Mikrotik router which I intended to setup for our place, but in the end gave up.
To Indihome's credit, any trouble we have had with our modems, due to whatever reason, and at least one time after it got hit by lightning, they replaced it free of charge.
The weird thing about Indihome is that they will get faster and cheaper packages, but you need to go into the office to change your packages. They seem happy to keep charging you at a higher price at a lower speed.
I was happy in the end to take a break from computers, but my kids were driving me nuts asking every five minutes if they could "download this". "install this game" and so on. At least I can remember when we didn't have internet to amuse ourselves.
