This is likely not an ISP problem. I did not have this issue before the patch and now I have it all the time. For those of you with RCN in America, I have spoken with them and they do not have any P2P restrictions that are related to traffic from FF14. I have a ticket open with them and they will be giving me confirmed results once they have the chance to have their engineers look at their gateways. I was told that I would be contacted within 24 hours
