Time out question

AreshAreshi

Hi,

we geting some warnning on our exchange server that says:

The average of the most recent heartbeat intervals [531] for request [Ping] 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.

where can I check this timeout on the Sophos? is this the same time out that we can see at a Real web server that we use for our exchange server? or is somewhere else?

    Hi Aresh,

    I know this setting from Zyxel for example but never needed it with the UTM. I bet there a a lot of variables, if you use WAF or NAT and if you use strict TCP session handling for example.
    There is an old thread from 2013. There is following written:


    cc [Enter]
    packetfilter [Enter]
    timeouts [Enter]
    ip_conntrack_tcp_timeout_close_wait$ [Enter] 

    Standard is 60 s

     

    Best regards

    Alex

    P.S. I would open a case at Sophos support.
