Hi all, It's said that TCP hole punch does not work if both endpoints come from 2 sub-networks, whose NAT are both implemented by iptables. I just want to make sure whether this is true. If so, what type of nat can iptables work as? full-cone, restricted, port restricted, or symmetric? Sorry if it's not appropriate to ask such a question here. Thanks in advance. -- Best regards, Tony Wan -- 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
