static nat and port forwarding

[Easy Rhino]

im looking for some advice from some networking pros here. i have 1 public IP address that my ISP provides me. my router is a typical one which assigns each host a IP. in the past, if i wanted a host to run a web service i would forward port 80 to that hosts IP address. it runs fine this way for some services. ive read about using static nat instead which seems to do the same thing. can anyone tell me what i am missing?

static nat maps 1 public ip address to 1 private. So basically you could have in and out access for a web server. But then none of your other devices could get internet access. SOHO routers commonly use multiple to one address and share it by using different ports.
