Wa-wa-what? I heard about port forwarding but I usually don't have hosting problems only crashes, but do I have to port forward? (I'm on a mac)
do you HAVE to port forward?
it depends on your router. if it supports universal plug & play - then no you dont.
if your router doesnt support it, then you will need to.
if you port forward anyway - then it doesnt matter what your router supports, things will just work
