Hmm I thought as much but I'm not really that up on socket connections to know 
whether a connection could share both TCP and UPD packet types.
This leaves me rather clueless as to why I don't get NOTIFY messages accross 
the internet yet I can connect, send and receive sql statements no problems.
Actually thinking about it now - connections to our sever accross the internet 
use SSL whilst local connections don't.
Could there be some sort of problem with SSL ?
I guess I can change the software to force local users to use SSL as another 

Other than that I'm lost as to what is happening to the messages....
