VPN DNS issue

When I connect to the VPN from either a Windows computer or IOS device I am not able to resolve my home DNS. The internet either does not work at all, or I am still being blocked by my employers web filter. Before the upgrade to UTM9 I was able to freely browse the internet and resolve my home DNS. Nothing has changed with the setup other than the upgrade to UTM9 and I believe the issues are related.

Hi,

On Windows,

1. are you running the VPN client with Administrator privileges?

2. What DNS servers does "ipconfig /all" show on Windows when connected?

3. which VPN client are you using on Windows and on IOS?

Thanks for the help BarryG.  Below are the answers to your questions.

1.  The VPN client is running with Admin privileges in Windows
2.  In ipconfig, the ethernet adapter is showing the local primary and local secondary dns servers and the PPP adapter is showing my home primary (astaro server) and home secondary (home ISP) server.
3.  The VPN client I am using for Windows is L2TP over IPsec and the VPN client I am using for IOS devices is Cisco VPN Client.

I am not able to resolve my home DNS

Please say what you see/experience to make you draw this conclusion.

The internet either does not work at all, or I am still being blocked by my employers web filter.

What do you see/experience when it doesn't work? What web filter?

Do you have an ASG at home? At the office? Which was upgraded to UTM9? What exact version?

Cheers - Bob
