Can't access Visual Studio project from IP, only http://localhost

I'm running a project in visual studio. I hit run and it launches IE pointing at http://localhost:1267

If I try to visit http://10.211.55.3:1267 (the machine's IP), I get nothing, even when visiting from the same machine. IIS7 works fine.

The machine is actually a VM running in parallels.

Any ideas what's may be going on?
