I would like to set my source port when I connect to the tor network. I know that the destination port is set irrespectively if you use a bridge or node to connect for out bound traffic. I would like tor to use a specific port all ways for the destination port for inbound traffic or source port for out bound traffic bound to a specific ip address. How can I do this? I am using tails.

I used this command echo Reachableaddresses IP:port | sudo tee -a /etc/tor/torrc it does not work still the source port is random
