Some flow guides go a bit deeper such as how a server/client reply to a packet but I wasn't looking for that level of detail Please check your router’s user manual or contact the customer service line of your internet service provider if you need help. This is the standard IP address for most routers, but yours may differ. Type in the IP address of your router into the URL line as: 192.168.1.1/.
