And if I only have 8 connections, I'm not accepting inbound connections? I have UPnP turned on + matching router, I thought this would be enough and that I am accepting inbound connections ... but I only have 8 total.

<p>There is a <a href="http://portforward.com/help/portcheck.htm" rel="nofollow">port checker tool that is not browser based</a> that will allow you to to check to see if the port 8333 is open.  I had a situation with my windows 2008 R2 VPS where i was stuck at 8 connections.  I went into the bitcoin client and unchecked "map using UPnP", shut down the bitcoin client, then went into windows firewall and added bitcoin to accept incoming TCP, UDP connections for the bitcoin-qt.exe.  Then I restarted the bitcoin client, and I had 20+ connections after 10 minutes or so.</p>

<p>I didn't even have to use the port checker tool.</p>
