Debugging in http://localhost:8082

Today I've made my first siebel project compilation, all my environment is brand new and well configured.
I've enabled 'Auto-start web client' feature and hit the road. IExplorer browses http://localhost:8082/ and inherent error. Why in God's name is this happening?

The answer is simple, (If my friend Alexandre didn't help me, it wouldn't be so simple), my Firewall is enabled.

After I disabled that, my debug can go on!!
