Hi
Having a problem with DHCP and DNS when using a VPN on Windows 8.1
All of a sudden last week we stopped getting DNS server IP's from the DHCP server on the VPN PPP service. We get and IP but no DNS settings.
As you can see below the PPP adapter dose not even list the option for a DNS server this is using a WiFi Hotspot off my phone
PPP adapter XXX VPN:
Connection-specific DNS Suffix . : XXX.int
Description . . . . . . . . . . . : XXX VPN
Physical Address. . . . . . . . . :
DHCP Enabled. . . . . . . . . . . : No
Autoconfiguration Enabled . . . . : Yes
IPv4 Address. . . . . . . . . . . : 10.254.1.33(Preferred)
Subnet Mask . . . . . . . . . . . : 255.255.255.255
Default Gateway . . . . . . . . . :
NetBIOS over Tcpip. . . . . . . . : Enabled
Connection-specific DNS Suffix Search List :
XXX.int
Wireless LAN adapter Wi-Fi:
Connection-specific DNS Suffix . :
Description . . . . . . . . . . . : Marvell AVASTAR Wireless-AC Network Controller
Physical Address. . . . . . . . . : 4C-0B-BE-02-4C-E2

Default Gateway . . . . . . . . . : 172.20.10.1
DHCP Server . . . . . . . . . . . : 172.20.10.1

DHCPv6 Client DUID. . . . . . . . : 00-01-00-01-1C-45-F4-06-00-50-B6-77-78-54
DNS Servers . . . . . . . . . . . : 172.20.10.1
NetBIOS over Tcpip. . . . . . . . : Enabled
I can only get the DNS working if I manually run the command
netsh interface ipv4 add dnsserver "xxx VPN" address=172.xx.xx.30
I've checked the DHCP server settings and and if I use a webpage on the sonicwall it uses a Aventail Smart Tunnel and I get a DNS server fine from the same DHCP server. Just the windows VPN dose not work correctly.
If anyone has any ideas?
