Pix 515e and Microsoft Exhange Active Sync Direct Push

[mikemayou]

Has anyone had any experience with configuration on the pix and Micrsoft Exhange Server using active sync direct push to mobile 5 devices with the messaging and security pack

I get the following error

The average of the most recent [200] heartbeat intervals used by clients is less than or equal to [540]. Make sure that your firewall configuration is set to work correctly with Exchange ActiveSync and direct push technology. Specifically, make sure that your firewall is configured so that requests to Exchange ActiveSync do not expire before they have the opportunity to be processed.

Modify the firewall time-out values for HTTP(S) connections to the Exchange server to be greater than the default time-out limit of eight minutes. On the PIX firewall, by default, the connection timeouts are set to 1 hr, which would be greater than the default time-out limit of eight minutes on the Exchange server.check this value on the PIX configuration.
