I have a laptop with a media server installed that I use for my home theater. In order to view my media on my mobile devices when away from home I have forwarded the port to the media server through my router. I also have my modem setup in bridge mode. Does this pose any specific security risk?

I have MSE installed and have the firewalls turned on in Windows and both the router and the modem. Is there anything else I need to do or programs I need to install for security purposes?
