Skype for business over Check Point Firewall

Hi Mates

I need an urgent help.

Has anyone has implemented skype for business over a Check Point Firewall?

I am trying to do so, but I am having issues with certificates presented to mobile devices (smartphones, tablets) when connecting to our internal SFB servers. The internal servers are present a self-signed certificate, hence they clients are unable to connect.

Thanks in advance

I assume, you have HTTPS inspection enabled on your FW. In this case, you need to bypass Skype for Business traffic. Depending on the version of Check Point you are using, there might be different ways to resolve it.
