Realm Error...

[billybobbo]

I can login to my own server but no one else can. Everything works but when they get to the realm selection, they select the realm then get kicked back to realm select.

Post your ascent-realms.conf

Make sure your realms.conf says DYNDNS:8129 at the bottom and as TheSpidey said, post your world.conf (blocking out the pass of course)

[TheSpidey]

world isn't needed, it sounds like a simple realms problem as you said. He probably forgot to replace his local IP with his external one / domain
