From North America, and I’m going on vacation in china for a few weeks. I wonder if anyone knows if I’ll be able to access any of my self-hosted services over zerotier while I’m abroad?
Edit: To be specific, I’m hoping to ssh into my machine over zerotier in case I need to fix something and back up some photos to my home NAS via rsync or something
It depends. Very much. And this is the main problem: There isn’t “one” solution, you will need a few.
The thing with the PRC is: Their great firewall isn’t “one big uniform block”. It’s fairly “variable”.
For example: In Beijing,even 10 years ago, I could access google maps and Facebook without any issues(back then highly blocked) as long as my mobile phone was roaming. The second I was on wifi of course it was blocked. But even the cheapo VPN my colleague had did work out fine. Until the day the police started to prepare for the party convention - then suddenly my colleague couldn’t get out, neither could I with our company wifi and even my carefully crafted wire guard over HTTPs didn’t work - unless I was in the wifi of the hotel or our host company. There it did. Party congress over? Back to normal operations.
If you travel through the country you will find that in one place solution A works, in another solution B. Generally the more rural (or closer to Tibet/Xinjiang/Myanmar) you get, the more restrictive it seems to be.
Personally I would simply get there different commercial VPNs to make sure you have a choice to get out at all - there are various ones with a good PRC reputation. Most providers have trials as well. And then double tunnel through that if you can’t directly reach your usual VPN at home
