Port forwarding can sometimes be a nerve-wracking problem. Though everything is set up correctly an IP Address can sometimes go unseen and the user keeps on clicking the save button but nothing works. Depending on which router is installed (Some routers are easier than others at setting up port forwarding rules) it can be easy to set up, but not easy to get working. Most routers, like Linksys, only let you put in the last part of the IP address to forward to (making sure the user doesn’t put in an internet IP instead). While other routers let you put the whole IP in (Some users accidentally put the internet IP instead of the Local IP in).
People can get confused about what IP address they should put in. Other times people may want to make a port forwarding rule for their devices or IP cameras and put the wrong IP in as well. To make sure the port forwarding rule is working correctly, the IP address of the rule should point to the computer, or machine, you want the connection to go to.
Some users have put internet IP’s in or just the wrong IP altogether. Why will someone put a wrong IP address as it is the most essential thing to remember while setting up port forwarding, you need to remember that a lot of home users are new to port forwarding and IP addresses. They don’t always understand the differences between a LAN ( a local network) and a WAN (the internet).
