и какво ми дава в iptables -L -t nat
Chain PREROUTING (policy ACCEPT) target prot opt source destination
Chain POSTROUTING (policy ACCEPT) target prot opt source destination MASQUERADE all -- anywhere anywhere
Chain OUTPUT (policy ACCEPT) target prot opt source destination
П.С. А в кой фаил трябва да ги напиша за да важат след рестарт ?
