Hello everyone

I want to know *how to* setup this types of NAT:
/-Full Cone NAT/
/-Restricted Cone NAT/
/-Port Restricted Cone NAT/
/-Symmetric NAT/

Using iptables, I set all policies to "ACCEPT" and I was able to setup 
two kinds of NAT:
(192.168.2.170 is my "public" address and 10.0.0.1 is my "private" address

/-"Full Cone NAT", with the following rules:/
iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to-source 192.168.2.170
iptables -t nat -A PREROUTING -i eth0 -j DNAT --to-destination 10.0.0.1


/-"Port Restricted Cone NAT", with just a single rule:/
iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to-source 192.168.2.170/

/
Now does anyone know how to setup Restricted Cone NAT and Symmetric NAT?

Thanks in advance
Pedro
