I think my ISP is blocking the port forwarding section of my modem, it's on the manual but when i open it on my browser it's gone, if I'll get a new router can i port forward on my router even if my ISP blocked the port forwarding on my modem?
Port forwarding is only required on routers and not modems, unless your modem is actually a modem/router combo (usually has 4 LAN ports and/or wifi).
If it's a combo unit, then adding a router will not help unless you can figure out how to bridge your modem (have it assign the public IP address to your own router).
