I get a bunch of these in my router's log:

Blocked incoming TCP SynAck packet from <remote ip>:<remote port> to <my ip>:<my port> with unexpected sequence

It only happens when another computer on the network is attempting to use a program that uses the same ports as FFXIV. The computer in question is accessing Facebook games... namely Zynga games. It's just weird to me that it causes my FFXIV session to terminate.
Hmmm my gf play ffxiv with me and i can only open the ports for one pc within the network so i open mine to download the update take less then 5min then open her ports and she download it. When she use to play facebook when i was playing beta1 i did see a lot of lag problem.

I hope SE read this and find a way to fix this i know a lot of ppl having same issue.
