Bind outbound ports
It would be useful if a tor relay could be configured to use a specific local port range for outgoing traffic, or even bind to a single port.
This would make tor more manageable and flexible. Especially in a router/fw.
Just like with have ORPort for incoming traffic we could have OROutPort for outgoing ports.
Many popular torrent applications does this.
It would allow running tor behind a stateless firewall, which is very useful for low end routers with high bw Internet connections.
