I grabbed an Oracle free-tier many moons ago. The x86 one with 4 gig of memory I think? The arm have a much more core and memory but unless you go with Pay As You Go (PAYG) account ( need a one time refundable $100 credit) it’s virtually impossible to grab it.
My free tier account is sufficient as pure VPN for accessing stuff, you get 10 TB/month egress traffic. The downside is it’s Oracle, and you are at their mercy ( they can purge it without notice )
I never tried it because CGNAT but maybe Dynamic DNS could also solve this.
Other than that, Tailscale / CF tunnel etc are a fine solution ( for now )
The simplest would be renting a VPS I think.
