To use P2Pool, you must be running your own local ecocoind. For standard configurations, using P2Pool should be as simple as: python run_p2pool.py
Then run your miner program, connecting to 127.0.0.1 on port 22337 with any username and password.
If you are behind a NAT, you should enable TCP port forwarding on your router. Forward port 9777 to the host running P2Pool.
Run "python run_p2pool.py --help" for additional options.
