HI, all: the command is "iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE" how to write the code using libiptc to implement this? It is hard to get enough useful information about programing with libiptc APIs, so can you give me the sample code ? thanks a lot! -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
