Running a Full Node through VPN? My ISP has blocked port 8333, due to the gigs of inbound traffic I incurred running a full node. Consequently, I would like to run a full node through VPN (specifically, OpenVPN with an OpenVPN provider).

Would I need to have the VPN forward port 8333?
Yes, incoming connections must be allowed through port 8333. If your VPN provider allows port-forwarding, it should be configurable in your account settings.
