There is a simple solution to this if your ISP provides it: You must use
the www-proxyserver of your provider. If you configure your webbrowser
to use this it makes no difference for your external traffic but traffic
to wonko will also come via the proxy and it will work fine.
If you have more domains on your server it's even the only way to test
it, I use it here also for three (small) websites.
