Node communication by public IP address

This works fine in a LAN but doesnt work through the Internet =( I opened
those ports on both side: 4369 TCP and 9100 to 9105 and typed on the erlang
console:
 application:set_env(kernel, inet_dist_listen_min, 9100).
 application:set_env(kernel, inet_dist_listen_max, 9105).

But when I try net_adm:ping(DistantNode) it doesn't work =(
Any idea?
