Can someone help me port forward? (i have spectrum)

I was making a server for me and my friend, he tried the same thing but cant log into his router. Since i can i decided to make one, the server works for me and everything but the issue im having is that i can connect but he cant. The server is on the server tab if he searches it but cant join, even through Direct Connect. Is there any help? (ill provide more info if i have to just reach out please)

Good news, we fixed it, turns out all i had to do was disable “Reserve IP Address” and turn it back on :slight_smile:
