I want my pool to be accessible from the public, i have forwarded port 9332 and 9333 on both udp/tcp, and its still not possible, and the system firewall is open for that, for example i cant access the pool stats through http://external_WAN_IP:9332 but i haven't yet tested using a miner and connect it to the pool.
i have set up the pool according to the instructions here http://p2pool.in with the latest version 14.0
