[Centos] Error in access internet from server...

Hi, guys

I have CentOS 3.4 I ping any host in intranet and internet from server I connect in server for any service: web, mail (pop,imap, smtp), dns, mysql, ssh with success but I can't use wget, curl, yum...

The connection always go to triying and nothing happens.

Maybe problem with routes? Iptables?

Thanks,

Tiago Bahi
