I trying to set-up a tor middle relay on Azure.
I've an Ubuntu instance, tor is all installed and has bootstrapped fine, but it won't form a circuit and the ORPort is unreachable.
I assume this is a firewall issue, and digging around on portal.azure.com I found the instances security rules.
Has anyone got a good how-to for setting the MS Azure rules up? failing that what ports do I need open (is it just the ORPort and 9050?)
