Portforwarding not working?

Router: (Netgear router FVS338)

I hosted a private Minecraft server and it went dormant recently, now I'm planning to reopen it again.

I know how to portforward, I did it in the past and it worked before.

Now that I'm trying to reopen the server, my peers have claimed that they can't connect to the server. I realized my port, 25565, is closed and I have tried to portforward again. No luck with the port.

I disabled my whole firewall to see if that was the problem, but again, the port was still closed.
