It really depends on how things are set up at your ISP. In college, we had dynamically assigned, but publicly accessible addresses, so I used a dynamic DNS service to tie the domain name to my computer. I used freedns.afraid.org (mentioned by someone else), though other options exist and many routers integrate with a couple services out of the box (often dyndns.org). You can check if this will work by finding out your public IP (type "what's my IP" in a web search) and checking if that corresponds to the IP on your router (should be the WAN IP). If it is, you're probably set, but you'll need to check to see if your ISP blocks any ports. To check, just set up something on your computer and mess with the port forwarding settings on your router to point to it, and then test accessing it from outside your network (easiest is to start a webserver and try to access it from your phone while running in data). If you can access services on your computer but your ISP blocks ports you want to use, call them and ask if those blocks can get removed. If not, you can get it to work by doing a reverse proxy using a VPS (good providers are Digital Ocean, Vultr, and Linode) to point to the ports your ISP does allow. If you can't access your computer at all, you have two options: 1. Ask your ISP if they offer static IPs (mine does for ~$5/month) 2. Set up a tunnel from your computer to your VPS (SSH tunnels, VPN, etc) Most ISPs either offer static IPs or give you a dynamic (changing), but publicly facing IP, so you probably won't need a VPS at all and just need to figure out the dynamic DNS thing. As for assymetric upload/download, it's really not an issue, sending lots of data one way will just be slower than the other way. There just isn't much you can do about it.
