Yes, so long as you know the risks involved in doing so. It is often necessary to use port forwarding on a firewall in order for some things to work. For instance, if you wanted to run a web server on your computer, you would need to forward port 80 and perhaps 443 to your computer that way other people on the internet could actually see it. Also, port forwarding is also needed for Bit Torrent. Bit Torrent will allow incoming connections on a port designated by the client's settings. If you do not allow incoming connections, you will not be able to upload the file to anyone else.
