Hi In our company, we have got one range IP public from our Internet provider. so I want to assign this range to our users.this range is 128 bit. Bu my concern is: 1- Do I have to set all IP public on output interfaces? Or iptables automatically adds all IP's on output interface? 2- Or maybe it is not necessary to add all IP's on related interface,if so , How does iptables do nat pool without adding IP's to related interface? Thanks for any help or guidance -- N.Chavoshi -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
