[Sunhelp] NAT on Linux

[Gregory Leblanc]

IP Masquerade is a type of NAT. Static NAT is where you take a block of IPs
on one side of your router (be it from RedHat or Cisco) and assign them to a
block of IPs on the other side of the router. E.G. I have a 10.0.0.0 with
a mask of 255.255.255.0 on one side of the router, and I call it 135.0.0.0
with a mask of 255.255.255.0 on the other side, each IP on the 10.0.0.0
block corresponding to an address on the other side of the router. ASCII
art...

_______________
 10.0.0.0-10.0.0.255 : 255.255.255.0 | ROUTER
| 135.0.0.0-135.0.0.255 : 255.255.255.0

|_______________|


IP masquerading is where you have a limited number of IPs on one side,
"masquerading" as any number of IPs on the other side. 

____________
 10.0.0.1 : 255.255.255.0 | ROUTER
| 135.0.0.0-135.0.0.255 : 255.255.255.0

|____________|

Does that explain at all?

I do think IP masque.. is equivalent to NAT.
