Reverse Proxy for OWA ActiveSync ?

[alig.norbert]

Hi there,
I'm looking for some solution to handle OWA publishing with some reverse proxy
function on the firewall. No Web Proxy on DMZ. No TMG and no directly NAT to the inside Exchange.
I have managed to do WebSSL with external portal and SSO on the ASA for Webmail access. ActiveSync (e.g. Ipad) isn't working through that kind of portal.

Any suggestions? Cut-Passthrough? Or who is facing the same issue, with TMG been discontinued? Fortigate and Sophos mentioned to handle reverse proxy.
How about Cisco?

Kind regards,
Norbert

Were you ever able to resolve this?  We're having a similar issue getting ActiveSync and OWA to work through a Cisco IronPort C170.

Only by NAT/PAT to a reverse proxy (Citrix Netscaler) in the DMZ.
Several installation are done with fortigate.
