go run > cmd >enter >ipconfig > enter
get your gateway something like 192.168.1.1 and your ip

type the gateway into your browser and it will ask for a pass word and user
prob just
user:admin
pass:admin
if not i dunno
then prob advanced options > virtual server or port forward or something look around till ya find it

and the rule will be something like

from:all ips
to: your ip
port from:7777 (or whatever you are gonna use)
port to:7777(as above)

hope that helps
