problem downloading ms-updates

[bhavin_bhatt]

Hi,

I am having problems downloading ms updates, as i have configured policies allowing users out going to microsoft, but when responding with updates, microsoft seems to be using som other websites, which seems to get blocked on the way back in, as the original destination (microsoft) has changed to some other site. is there anyway to fix this, i have attached a screenshot of the error. note, the drops are from outside, coming to inside (the response to a users download request from microsoft).

Please advice

Cheers

Bhav

Please see a sample request to ms update from the user attached.

Hello,

Via the egress filter, are you permitting access to specific IP's, along with the ms-update application? If you are ACL'ing access via IP as well as Application, then content for updates hosted on various CDN's (Content Delivery Networks), i.e. Akamai, etc... will be blocked unless IP's/subnets are added to the ACL. (though CDN IP’s are typically dynamic as well with servers hosting content responding based on lowest latency, etc…)
