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?

    I'll try and post a screen cap later.

    I'm wondering if this is a WPAD/Proxyconfig.pac issue.  We use both on our internal network so that sites (like our exchange servers) are connected to directly - this works fine for us.  Our VPN clients get their IP's either using a static IP set on their domain account, or assigned by UTM from the VPN L2TP pool.  My question: in this situation, when a client connects via VPN would the WPAD.DAT or PROXYCONFIG.PAC scripts be obeyed?

    Do you use Exchange 365?

    I had an issue which bugged me for weeks, until I found out that this was an issue as Microsoft were changing a few settings, and this exact error would appear.

    it appears every now and again when using Outlook, it is usually when (back-end) servers change and the certificate is not trusted.

    Sorry no - our exchange is on premisis, and I know the certs are fine.  As I said, this ONLY happens when a user intiates or drops a VPN connection to the company network.
