I sometimes need to allow people into my development version of my site I keep locally on my computer. I have a DNS subdomain that points to my local site so others can get to it, but I have to allow them full access through my firewall.

If I just allow access to the http port, it doesnt work, I have to give their IP full in and out access, and obviously there are BIG security concerns.

Is there any other thing I can? Other ports that need to be opened other than just the http port?
