Apache: It's possible to change ports around, right?

[Greg the dogsitter]

On our server, Rails runs on port 12001. However, our corporate firewall blocks that port. It should be possible (never mind how) to get around that, right? Redirect from port 12001 to 80, or something like that?

No details necessary; I just need to know that this is, at least, possible.

Thanks!
