ASA 5505

Dears,

I have 5505 ASA , and I tray to use it just to filter the traffic for two application servers which use port http and https, so after I made the static nat and the access-List the servers didn't work, I'm not sure about the Problem, so look in the following configurations and tell me if there is any thing wrong, notice that we even can't reach Internet from the two servers.

((The System consists of two server must Nated with two real IPs to Internet))

Hi Ahmed,

At a quick glance, your config looks okay to me.

Can you trying pinging from the ASA itself? Try the 'ping 4.2.2.2' command and see if you get any replies.

If you see no replies, make sure the configuration of your outside interface is correct (i.e. do you have the correct IP address and subnet mask configured based on what was given to you by your ISP?).

Hope that helps.

Try to remote "access-group 102 in interface inside "

from high security level to low security level do not require acl that is stateful.

If add acl, it require permit http and https in inside interface.
