I have run a netstat -a -o -f - here is the output for the PID Sins is running under
TCP 192.168.1.2:58506 38.98.152.153:7000 SYN_SENT 772
As I said, the out port keeps changing
[EDIT] After waiting a few minutes and trying again
TCP 192.168.1.2:58567 38.98.152.153:7000 SYN_SENT 772
I understand that it is picking a port on my machine to talk to the 7000 port, but I have no idea why it is being blocked....
