So I started an FTB Unleashed server on my computer. I portforwarded my server with the port 25565, and I can connect fine from my client Unleashed using localhost:25565. Everything runs fine, all the mods are on there, it's great. But, when my friend tries to connect using the IP I got from whatismyip.com and the port 25565, it does not connect, he can't find the server. What am I doing wrong? Please help.
P.S.: I ran a terraria server in the exact same way using a different port-forwarded server set to the 7777 port and that works fine and he can connect.
