I would like someone to help me and tell me how i can open any port on my modem ( i don't have router).

ty in advance

Usually modems so not have blocked ANY ports but I can be wrong. Could you describe your network situation?

maybe firewall

Youre not able to forward any ports if ure using a modem.

Only routers with a built-in softwares may do that.
