While trying to connect through IPv6 I get
Data too long for column 'ip' at row 1
so it seems that you need to increase the size of the column that stores IPs (46 chars should be enough, check http://stackoverflow.com/questions/166132/maximum-length-of-the-textual-representation-of-an-ipv6-address for more info). Connecting through an IPv4 only tunnel works (this post is the proof).
