Aha, I think I misunderstood your situation then? I assumed you’re running these routing rules on your client machine, so you’re able to access your ssh server without it going over the VPN – not that your server is running a VPN active that blocks external connections…?
But if I didn’t misunderstand, I’d mean the (assumingly static) ssh server’s IP.
Yeah, but many European countries have moved to require registration of prepaid cards “to stop criminals” or something like that. So you can still usually buy them with cash and whatever, but you won’t be able to activate or use it until you confirm your identity.
That’s an inherent problem with shared connections.
The thing with sites telling you that your login is incorrect is also sometimes intentional, so people trying to brute-force logins won’t realize they’re getting blocked or just that their attempt was incorrect.
And yes, the only possibility is to try a different server that hasn’t been abused, or run your own.
I assume you just leave the keyring on your desk/in some drawer? I had handcuff keys on my normal ring and the pointy thing on the keys (for double-locking) made holes in my jeans, so you’d be crazy to go around with those for opening SIMs in your pocket.
