tekkit V.2.1 on server and 2.1 on launcher

server:Ubuntu server 11.04 Computer:Mac OSX

latest java version

When my friend tries to join the server from a remote location it gives me the error sttated below. When I try to join from inside the network of the server I have no problems. What did/didn't I do?

UPDATE: my friend just told me that when he joins nothing renders, but for me it's fine, and he also said that it's only at certain areas, when he comes near me the problem goes away and it renders properly

Well with local host i seem to be able to play without any problems, and also remote host, but it's only my friend computer/account. I looked on bukkit forums and people say there is no fix >:(
