@"FunkyG" Not really saving the day, but defintly trying to help! The only way to know for sure (I think), I'm not a networking specialist but a programmer, is to scan incoming traffic with Wireshark.
Also keep in mind that the router (in 99% of the cases) also keeps a log file. It could be disabled by default, but usually it isn't. If OP posted that information here it could be of great assistence too.
@OP, if you post shit like that don't forget to remove/black-out personal information that you don't want SL members to see.
