Hi i have configured web vpn on cisco asa 5510, and able to access Exchange server for OWA.additionally i have Fortigate and fortinalyzer in the same inside lan same as exchange server.However i cannot access them.when access fortinalyzer, login page appear, uopn log in it display server unavailable.in the case of Fortigate, it doesnot evenprompt the log in screen.(Fortigate firewall operate as transparent proxy).I just need to know where ASA web VPN support only web servers and not every HTTP(S)or i am missing some thing.
Clientless functionality on that version was quite limited, and as there is re-writing involved, it can cause issues. 8.0 has much improved clientless functionality and may be worth a look, however, it does require you to buy additional licenses, as only 2 are allowed by default, unless you already have bought licenses for webvpn.
The only thing I can think of is that the Fortigate is not allowing the traffic from the ASA. I have never worked on a Fortigate, but make sure you are allowing management of it from the ASA's internal IP.
