Question regarding certificates generated by Astaro...

Shaun Raven

Hi,

I've published my exchange server through UTM successfully. 

Sometimes my users will get an outlook error regarding an untrusted certificate if they connect/disconnct a VPN session.  That certificate has the following netscape comment...

 

"Generated by Astaro HTTP Proxy"

 

Can anyone tell me why this might happen?

    Not sure, but it looks like once you connect through VPN your client's HTTPS traffic is decrypted and scanned and thus it will send traffic back using its proxy certificate.

    Managing several Sophos UTMs and Sophos XGs both at work and at some home locations, dedicated to continuously improve IT-security and feeling well helping others with their IT-security challenges.

    Sometimes I post some useful tips on my blog, see blog.pijnappels.eu/category/sophos/ for Sophos related posts.
