1. Open a terminal (Ctrl-Alt-T)
2. Type the following command:
sudo ufw allow from <your_device's_ip> to any port 5001This assumes you are using the default PS3 Media Server port of 5001. For example, if your PS3 uses the static IP 192.168.0.100, then do:
sudo ufw allow from 192.168.0.100 to any port 5001If you aren't using static IPs on your devices but wish to open the server to any device connected to your router/subnet, you can specific a subnet mask, e.g. 192.168.0.1/24. If you're not using Ubuntu but are using iptables with your preferred linux distro, simply add an exception for port 5001, e.g.:
sudo iptables -A INPUT -s <your-device's-ip> -p tcp --dport 5001 -j ACCEPT
sudo iptables -A INPUT -s <your-device's-ip> -p udp --dport 5001 -j ACCEPTThis ought to do the trick.
