For seeding? Out of luck as I don't have a VPS currently, I used one to open my ports with some hacky ways using Wireguard and IPtables stuff, if there is a better way I would like to know lol.
Now I just constantly seed in hopes that people with the ports opened can access my stuff.
For accessing my files, Zerotier and Tailscale have been a godsend.
I also happen to have IPv6 support and I can access some exposed services through it without too much hassle, Plex and Bitwarden are two big examples.
