I signed up to <a href="http:&#x2F;&#x2F;nanovz.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;nanovz.com&#x2F;</a> out of curiosity and, well, it works. It&#x27;s €1.50 per year and you get 20 mapped inbound ports on an IPv4. I definitely wouldn&#x27;t trust it far for the price but I&#x27;ve almost had my full year out of it so far :-D I learnt about it via <a href="http:&#x2F;&#x2F;lowendbox.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;lowendbox.com&#x2F;</a> which is a blog that focuses on ultra low cost hosting and VMs.
