Experts: I need your help. We have installed ASA 5505 in Production without using any IPS, Proxy. All Inside users are able to access Websites except only www.adminitrack.com. I have checked the DNS and its resolving. When I do telnet (telnet adminitrack.com 80) then it doesn't block and trace route is also reachable. I have reviewed the Firewall Logs but still all connections making and nothing found anything wrong in the FW.
I used my laptop and connect with directly with switch which is installed between ASA FW and ISP router and allot one public IP to my Laptop then I tried but still its not accessible. We have other DSL connection of other ISP and when I change my gateway and assign the second gateway of the II nd ISP then website works fine. For this, I launched a complain in Ist ISP and as per them, they are able to connect with Telnet and also reach by trace route. Can anyone advice me what should I do to check??
