Recibí este error cuando quiero restaurar mis reglas de iptables desde un archivo.
iptables-restore v1.4.21: The -t option (seen in line 5) cannot be used in iptables-restore. Error occurred at line: 5 Try `iptables-restore -h' or 'iptables-restore --help' for more information.Ahí está mi iptables:
*filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -t nat -A POSTROUTING -o eth0 -j MASQUERADE -A FORWARD -i eth0 -o lxcbr0 -m state --state RELATED,ESTABLISHED -j ACCEPT -A FORWARD -i lxcbr0 -o eth0 -j ACCEPT COMMITNo puedo hacerlo sin la opción -t.
Lo resolví:
*nat :PREROUTING ACCEPT [0:0] :INPUT ACCEPT [0:0] :OUTPUT ACCEPT [1:76] :POSTROUTING ACCEPT [0:0] -A POSTROUTING -o eth0 -j MASQUERADE COMMIT *filter :INPUT ACCEPT [95:5492] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [48:3648] -A FORWARD -i eth0 -o lxcbr0 -m state --state RELATED,ESTABLISHED -j ACCEPT -A FORWARD -i lxcbr0 -o eth0 -j ACCEPT COMMIT
