osmux: Send the CI as part of the dummy to help to identify a client

Browse Source 
We need to discover the remote port as we are likely behind a NAT.
Right now the NAT code will just send to port 1984 on the BSC but
this might not arrive at the BSC. Include the CI (in the future we
need to include the endpoint address or send the dummy to the net
port). This is just an interim solution.
