- Get a separate IP for the node. Do not route your own traffic via this IP While it may be tempting to mix in your traffic with your node's exit traffic for cover, this is best avoided. Having a separate IP allows your ISP to more easily recognize that abuse complaints and DMCA notices can be forwarded to you to be quickly responded to with a boilerplate response, as opposed to cutting off your Internet access or providing your personal information to the copyright cartels.
I know that this is the recommendation for an exit node, but can I run OpenVPN and a Tor relay on the same machine, using the same IP address? I can't see why not, as Tor relays do not route traffic to the outside world, but I thought I'd ask, just to make sure.
