Answer 1

Bigb is right, recaptcha do requires port 80 to communicate with google servers.

You need to add proxy server setting for recaptcha in your web.config file

Example Taken from here

<system.net>
<defaultProxy>
<proxy usesystemdefault = "false" bypassonlocal="false"
   proxyaddress="http://ntproxyus.lxa.perfora.net:3128" />
</defaultProxy>
</system.net>
