Internal IP via APM unable to browse intranet sites

Dear all, encountered a weird scenario.

 

WebTop portal links work well and when I do a telnet port 80/443 from F5 CLI to various internal sites, connection was a success. (via F5's internal self-IP Automap)

 

When users receive an internal IP (This was needed because of mobile phone-only users) and tried to browse to the sites directly by entering the URL, it couldn't connect. When I tried telnet port 80/443 to these URLs, connection failed.

 

The internal IP lease pool and F5's internal self-IP are in the same subnet.

 

Anyone encountered such problem before?

      at first it was automap but it wasn't working. Following Stanislas Piron's advice, I check boxed "Proxy ARP" and SNAT must be disabled. Thanks for your input!
