Just turn the firewall of will not help. 99% of all home routers will use
Network Address Translation (NAT) and Port Address Translation (PAT)
i.e. you got one external/public ip-address on the router and an
internal ip-address
on your computer. So if you want to access your computer from internet you
need to translate the external ip and port in the router to your
computers ip and
port. It should be something like "port forward" in the router that
you need to configure.
