Don't specify IP address if you don't have to.

Other than the host syslog-ng is running on won't get the network
traffic ?

Nothing other than the above, as at this point you're not doing any
change to the system as the NIC is still down.

Of course it can't start because no program can bind to IP addresses
not owned by the host the program is running on.

What do you want to achieve? Please clarify your question.
