Hi Dimitris

You forgot to assign the ACL to interface

access-group outside_in in interface outside

Dimitris,

Try running " clear xlate ". This will drop connections temporarily. If doesnt work, try "no fixup protocol http 80". If stilld oesnt work, please attach your full config with IPs and without the encrytption hash of your enable and user passwords.

The second configuration you attached doesn't even have static translations. I don't like to use letters so let's suppose the private IP of the server is 192.168.1.1. You're using the IP address of the outside interface so:

static (inside, outside) tcp interface 80 192.168.1.1 80

access-l outside_in permit tcp any interface outside eq 80

access-g outside_in in int outside

clear xlate

If you're still unable to access the web server, you need to run traffic captures in order to figure out what the problem is.
