Hi,

Thanks for all your inputs/feedback.

 My 1st question again is that let's say that question only ask to allow
outside users access webserver via www.xxxx.com and inside users access via
http://x.x.x.x:80, for that we use as follows:
 nat (inside,outside) Nated_IP, real_ip dns

So, do we also need to have acl on the firewall to allow http/https
 access-list outside extended permit tcp any host <nated-ip> eq 80/443

thanks
Pemasiri
