Answer 1

Vincule o soquete de escuta e as conexões de saída a esse endereço de interface de rede.

rtorrent -b a.b.c.d

Bloqueia todas as portas exceto a faixa de porta de 49164 a 49164 (intervalo de porta padrão)

iptables -A INPUT -i "Interface (ex. tun1)" -j DROP
iptables -A OUTPUT -i "Interface (ex. tun1)" -j DROP
iptables -A FORWARD -i "Interface (ex. tun1)" -j DROP

iptables -A INPUT -p tcp --sport 49164:49164 --dport 49164:49164 -i "Interface (ex. tun1)" -j ACCEPT
iptables -A INPUT -p udp --sport 49164:49164 --dport 49164:49164 -i "Interface (ex. tun1)" -j ACCEPT
iptables -A OUTPUT -p tcp --sport 49164:49164 --dport 49164:49164 -i "Interface (ex. tun1)" -j ACCEPT
iptables -A OUTPUT -p udp --sport 49164:49164 --dport 49164:49164 -i "Interface (ex. tun1)" -j ACCEPT
