I have a Motorola modem which is connected to a Verizon Actiontec MI424-WR Rev. I. I cannot seem to get port forwarding configured what so ever. I have a Raspberry Pi on port 8080 that I want forwarded to. I know that I'm setting it up correctly, but every time I use a port checker tool, it states that the port is closed. I know that ISP block certain ports, but I don't think that is the case. I think the problem lies within the modem/router configuration. Thanks in advance.
