Configure firewall according to Solana recomendations

1. Allow TCP/UDP connections for the port range 8000-10000: sudo ufw allow 8000:10000/tcp; sudo ufw allow 8000:10000/udp
2. Deny TPC/UDP connections for the port 8899: sudo ufw deny 8899/tcp; sudo ufw deny 8899/udp
3. Deny TPC/UDP connections for the port 8900: sudo ufw deny 8900/tcp; sudo ufw deny 8900/udp
