outgoing ssh but not ftp/http does not make sense to me, except if you have set some proxy for http/ftp and forgot about it.

well.
Incoming is FINE. Outgoing nope. not SSH from server to another host, only TO server that has this problem.
no proxy/firewall.
black magic?? hehe

Most likely it's your GATEWAY.
Also, route isn't very useful by itself, the output of "route -n" is more useful.

No errors in server, but i think exists an error in router.
if I try get document in another comp in the same network class I do it with successfull
I will put this computer in another class... aff
Thanks by attention...
and if someone need help, I stay here! With a poor english but some of interest :-)
I need to give back 2 cents that Tru given me! :D

Did you setup firewall rules when you installed the system? An iptables -L -v might shed some light. Just a thought.

yes, I have a name server running, but I alter resolv.conf to search cedaspy.com.br nameserver 200.175.11.2 nameserver 200.175.11.3
I alter routes to GVT backbone AND BrT backbone
