Thankz, brother, it worked. I need the nat to work with the firewall config
of the other school. Then, I saw in the log that the traffic going through
the 10.10.0.50 (my if) to the servers was being blocked. For me saying that
adm_net should communicate with cefet_server would be enough to the firewall
understand that it should pass trough any if on the way.

I know my config is far away from a good config but it's the first time I
configure an firewall, and I have only basic english knowledge, I'm not
totally sure about I can and I can not do, even since I read the tutorials,
because my english skills aren't good enough. The "IN" and "OUT" stuff is
very confusing for me yet.

But thankz a lot, it's working now.

Hugs,
Alaor Neto
