hi , are there commercial port forwarding service available?

like, I want to set my domain ABC.COM to 1.2.3.4 and 1.2.3.4 service will foward whatever request to my real webserver's IP address.

I understsand direct forwarding will expose my webserver's IP, so I'll do another localhost forwarding in my webserver.

ya know, instead of getting a VPS. cause I plan to get 10-20 accounts worldwide, vps is too expensive for the volume im getting.

any suggestions? thanks in advance
