Windows IPSec client not getting/using DNS
-
We've had IPSec working well for a long time, with clients on multiple OSes.
But there's one Windows user that doesn't seem to be getting/using our internal DNS.
For example, when he connects to our VPN and does ping www.mycorp.com he gets the public IP instead of our internal 10.1.1.x IP.
Strangely, his
ipconfig
output shows:PPP adapter MyVPN: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : MyVPN Physical Address. . . . . . . . . : DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes IPv4 Address. . . . . . . . . . . : 10.1.2.13(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.255 Default Gateway . . . . . . . . . : 0.0.0.0 DNS Servers . . . . . . . . . . . : 10.1.1.1 NetBIOS over Tcpip. . . . . . . . : Enabled
The "DNS Servers" value (10.1.1.1) is the expected internal pfsense LAN IP.
So I'm stumped as to what the problem is...
