Arris routers are simply amazing and they offer so much to the users that are unmatched in terms of utility. One such feature is port forwarding that allows you to not only dedicate specific ports on a router/modem but also make it work through different sorts of servers by forwarding the data and stuff like that.
Port Forwarding is also used as the major factor for hosting gaming servers and similar situations. It works out flawlessly, but if there is some sort of issues and port forwarding is not working for some reason, here is what you will need to do.
Arris Port Forwarding Not Working
1) Configure the right port and IP Address
Well, first thing first and most major issues that are caused by the port forwarding are due to the fact that it has not been configured properly. There are far too many things here that one needs to be careful about while dealing with something important such as port configuration. So, you need to make sure that you are configuring it in a perfect manner. To start that, make sure that you have physical access to the server that you want to create and use. Now, make sure that the correct ports are configured and that the correct IP address of the server is listed in the settings.
Now, you will need to check the IP and make sure that it is on the right port as well. If some other IP address is listed that is connecting you over the internet, you will need to fix the port now and enter the correct number there. This will get the issue resolved for you in no time at all and that will help you greatly with the problem.
2) Configuring Gateway
The default gateway plays a key role in optimizing the port forwarding and you need to ensure that you are able to make it work in the right manner. So, check for the default gateway and if you are seeing the connection failure error on your screen, you will need to rectify it according to the port and IP address that you have administered before. This is going to make it work flawlessly, and you will not have to worry about Port Forwarding not working again.
3) Check on Server
If you are unable to make it work even after double-checking on all the options above, then there is not much on that part and there must be some error with the server. So, check on that and make sure that the server you are trying to set the port forwarding for is active and has the port forwarding option enabled. This will solve the problem optimally for you and you will not have to deal with this mess again.
4) Update the Firmware
Once you have tried out everything above, the last thing that remains is firmware and there are multiple reasons that it might not be working. The most major one being the outdated firmware version and a firmware update should be enough to get it rolling.
