I discovered this too von StevenCaos Blog

Since then, others and I have not only made an attempt to contact these services about the problem connecting to Global Maplestory, but we have also contacted Nexon relating to this via service. Both services MS2 Mesos explained that they might no longer connect either even after running a number of tests and trying different things. I've gotten mixed answers from Nexon. I really don't think the first one knew what I was inquiring as he said he'd pass it on to the programmers. I tried again a couple months later and was met with another reaction.

Because you can view them seem to believe it's exactly like any other personal network. VPNs are clearly contrary to the TOS and while W[tfast and Battleping are equally private networks they alone should not be blocked as they are utilized by thousands of gamers who suffer from high latency. Battleping also uses the users IP address to login before linking via the US server which Nexon would be able to see I would assume.

He also says the game should be playable without these services providing you have a broadband connection that's really not correct. With no solutions the overall gameplay experience is not smooth. There are noticeable delays in strikes and buffing. Also attempting to pull off a double flash jump close to immediately is impossible without these services.

You merely need to unblock them. I discovered this too. Because you can see that this is quite recent. I really don't know if they're still attempting to have it working with the development group but a phrase on this could be fine.

They support 80+ MMO games and if you go to some of their forums and ask if the use of these services such as Battleping is allowed they'll all tell you that it's. There is absolutely no reason why these ought to be blocked. Not everyone who's in GMS service place is about 20-50ms ping. Some of Buy Maplestory2 Mesos us have 200+ms ping especially from Australia.Please do something about it. Maybe get into contact with these and see whether you can restrict access to such providers only.
