Hello,
Pedro Gonçalves a écrit :
I want to know *how to* setup this types of NAT:
/-Full Cone NAT/
/-Restricted Cone NAT/
/-Port Restricted Cone NAT/
/-Symmetric NAT/
Again ? I thought I already answered the last time you asked.
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
[...]
/-"Port Restricted Cone NAT", with just a single rule:/
iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to-source 192.168.2.170/
This is "symmetric NAT", not "restricted cone NAT".
Now does anyone know how to setup Restricted Cone NAT and Symmetric NAT?
AFAIK, you cannot do "restricted cone NAT" nor "port restricted cone
NAT" with the stock Netfilter/iptables. It would require dedicated
conntrack and NAT helper modules.
