Unable to access the internet when connected to Azure Virtual Network VPN

Hello,

I am using a point-to-site Virtual Network to connect to my Azure VMs.

The virtual network subnet is 10.43.38.0/24.
I can connect without problem using the VPN. But when I do, I loose my internet connectivity on my workstation.

My local network subnet is 10.100.0.0/16.

When I look at the routes on my workstation, I notice a route 10.0.0.0 that should not exist.

Pv4 Route Table

Active Routes:
Network Destination        Netmask          Gateway       Interface  Metric

         10.0.0.0        255.0.0.0       10.43.38.0       10.43.38.4     11

       10.43.39.0    255.255.255.0         On-link        10.43.38.4     28

     10.100.110.0    255.255.254.0         On-link     10.100.110.23    266

I removed it, which gave me back the connectivity to the internet, except I cannot resolve hostnames names: it's like my workstation doesn't use the correct DNS server.

Does anyone has any idea why the VPN connection adds this 10.0.0.0 route and why I cannot resolve hostnames?

Thanks you for your help,

Regards
