I cannot help you for the missing port, but:
Are you using Ralles modpack or have you loaded these mods personally, I'm asking because Ralles pack has exactly these 3 mods combined together, and others may also experience your problem. Ralles thread is here:

Because I also play this mod combination I'm interested in a solution too.
Cheers,
