webprotection settings for O365 + skype for business

funki_sahib

Morning,

 

which settings (exceptions) on the webproxy do i need for both services? we want to use O365 (outlook on client, also skype video and normal phone call)

when i look at the websites from microsoft i see there a lot of complete networks which has to be accessible for clients. also a lot of ports and also fqdn.

but are all of that needed for this?

 

when anybody can explain me how they setup their utm, it would be great. thanks.

    Mike, these are outbound only, so a general firewall rule like 'Internal (Network) -> {ports} -> Internet : Allow' should be all that's necessary.  Since the UTM firewall is stateful, it will keep track of the connections it makes and automatically allow responses, so no inbound rules are needed.

    Cheers - Bob

    Right.. But in a company with 4500 employees and 7000+ devices we aren't going to allow Common ports for skype/ms to be allowed outbound to any public ip address. We need to restrict them to MS/Office365/Skype/ Public ip addresses

    I agree 100%, Mike.  Do you already have a solution in mind?  How many locations are involved?

    Cheers - Bob

    Sadly, the only solution that i could find (support, forums, sales engineers) was to add all 300 ip/ranges to the firewall. Luckily the SUM server can reach most of the firewalls in place, but its really fustrating that sophos is lacking so many config options that other firewall vendors have and have had in place for long while.

     

    There are 7 Sophos firewalls and a bunch of Sonic walls. But those numbers will drop as they are replaced.
