Abstract:
1. A method for enabling communication between first and second network nodes ( 1 , 7 ) by way of a network address translation device ( 3 , 9 ), which network nodes are each capable of communicating with a server ( 11 ), which method comprises the steps of: causing the first network node ( causing the first network node to establish communication with the second network node by way of the network address translation device ( causing the server ( causing the second network node to establish communication with the first network node by way of the network address translation device, which step includes sending a plurality of second dummy packets from the second network node directly to the first network node, transmission of the second dummy packets overlapping with transmission of the first dummy packets; thereafter exchanging data directly between the first and second network nodes; the method including the additional steps of: determining an error if communication between the network nodes ( in the event that an error is determined, effecting an error auto-reconnect procedure comprising the following further steps:
