Essentially "Double Natting" is what happens when you place your computer behind a NAT router which is itself, behind another NAT router.
Occasionally it just happens, particularly in corporate environments where you want a small network to be isolated from the corporate network it's on, which in turn is isolated from the internet that it's connected to. While it slows things down just a tad, in practice, most, though not all, things work just fine across a double NAT.

Hi !!!!
This is must due to the Double Natting.
Yes you can turn off NAT in your secondary Router and the Main Router's Router will act as DHCP server assigning static ip to the clients connected to it..
On the secondary router , you can assign static ip in the Range of the First router and then disable NAT

Posted by: andy at June 7, 2006 6:45 AMI have a fiber internet connection which terminates and connects to a netgear natting router and the router connects to the switch on which all the computers are connected. At present I have provided the ip address of the netgear router as default gateway to all the computers. Since the number of users increased it has become difficult to trace the activity as the console which I use to control the router doesn’t have many features. For example if I would like to block yahoo for a particular user I cannot. My question is weather I can have double natting or not?
What I mean is that will it work if I have a computer with two lan cards and the natting routers connects to the one lan card and the other lan card connects to the switch and then install software natting like kerio winroute firewall and computers on network will use ip address of that computer as gateway which will have two lan cards so that I can manage the activity of all the users using the software firewall.
My service provider doesn’t allow directly connecting the rj45 utp to the lan card on a computer.
