Cisco ASA 5505 change protocol 443 timeout value ?

Cisco ASA 5505 change protocol 443 timeout value ?

Hi all,

I have installed Cisco asa 5505 as our company's firewall, and  from that day people with mobile devices started complainign that email is not working properly anymore. When i checked the server log i can see errors loged:

"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.  For more information about how to configure firewall settings when using Exchange ActiveSync, see Microsoft Knowledge Base article 905013, "Enterprise Firewall Configuration for Exchange ActiveSync Direct Push Technology" (http://go.microsoft.com/fwlink/?linkid=3052&kbid=905013)."

So it is quite clear that cisco is terminating 443 sessions to early.

I am after spending 3hours on google, but cant find a simple answer how to increase 443(https) timeout value on cisco asa 5505 firewall?

Getting frustrated here. So is there a simple command u use to change timeout value for protocol 443 through firewall ?

Thanks in advance !

RE: Cisco ASA 5505 change protocol 443 timeout value ?

try under Global Timeouts.

Firewall / Advanced / Global Timeouts

Try setting the Connection and Half closed to 00:00

RE: Cisco ASA 5505 change protocol 443 timeout value ?

you should be able to do it using MPF

class-map https

match port tcp eq https


policy-map global_policy

class https

  set connection timeout tcp x:x:x
