Anyone know how to make exceptions for Splashtop?

Hello Christian Sosa1,

Thank you for reaching out to the community, ensure Port 443 is open from the upstream appliances/devices if any including ssl and non-ssl traffic.
You can create an exception list for Splashtop: https://docs.sophos.com/nsg/sophos-firewall/18.5/Help/en-us/webhelp/onlinehelp/AdministratorHelp/Web/Exceptions/index.html

Hello there,

Thank you for the information, i believe some of those I did not have before in my exception. 

I am still not able to use Splashtop while SSL is enabled. 

Still need a way to disable SSL for Splashtop

Any other suggestions?

Hi,

have you disabled audio and video scanning in web extras?

Splashtop uses “Web Socket Protocol” which is currently not supported with SF OS.

Due to this reason with HTTPS scanning Splashtop may not work behind the XG and as in work-around, you need to add the Splashtop Web URL in bypass via FQDN based rule or with web exception rule with separate category guided by  Vivek Jagad

That website has always been green checkmark for us

https://www.splashtop.com/check

It's unreliable. Our remote desktop using splashstop does not work even if it is displaying all green. We must leave the network and then it works immediately.  

rfcat_vk I have not disabled this. Where would this be under? I do see audio and video under Web>File Types

BUt I do not believe this is what you are referring to.

Hi Christian,

please see below.

Hi Christian,

please see below.

Thank you!

You must be on a different subscriptions or higher end firewall. We do not have that option or we have not enabled the necessary dependencies. 

Yes, you do, it is in the advanced settings which I have shown expanded.
