GlobalProtect network adapter sets up IPv6 default DNS servers

[Carracido]

Hello community!

I share with you an issue, hopefully you can give me some ideas to fix it:

When connecting with the GP agent the virtual network adapter always sets up the default IPv6 DNS servers:

Ethernet adapter Local Area Connection 2:

Connection-specific DNS Suffix . :
Description . . . . . . . . . . . : PANGP Virtual Ethernet Adapter

 DNS Servers . . . . . . . . . . . : fec0:0:0:ffff::1%1
                                               fec0:0:0:ffff::2%1
                                               fec0:0:0:ffff::3%1   

After some reconnects the adapter gets the right IP. 

In the gateway it´s configured a primary DNS server to be forwarded to the GP agent and in GPS and GPA logs I always see that the primary DNS server configured in the gateway is properly forwarded to the agent together with the rest of the parameters. 

Any idea about why this is happening?? 

Many thanks in advance!

Marcos.
