Hmm. 0.0.0.0 is a wildcard address, meaning any of my local addresses.
I do understand how that works for binding a TCP socket you will be
listening on. It just means accept TCP connections on all addresses.
The destination address of the incoming SYN segment will determine which
one to use. However, which of the local addresses should be used
when calling connect() with 0.0.0.0? How should this choice be made?
