I solved part of the problem.
Now I can access the vm01 http page from the outside if I use the same port (80).
iptables -A PREROUTING -t nat -p tcp -i eth0 --dport 80 -j DNAT --to 10.0.0.1:80
When I try to redirect from the outside port 8080 to the vm01 port:80 I don't have a conexion.
iptables -A PREROUTING -t nat -p tcp -i eth0 --dport 8080 -j DNAT --to 10.0.0.1:80
Is there any problem with DNAT?? I read the netfilters tutorial and they say it is possible.
Thanks for any help.
