<p>I want to send http requests from a fixed, outgoing port. How can I do this in Go?</p>

Having fixed ports would make the SDN flows easy to configure.</p></pre>xandout: <pre><p>For the most part you don't set the outbound port for any communication. Your OS picks a random, unused high number port and you use that. </p>
<p>If you can tell us the underlying OS it may be possible to find a solution. </p></pre>
