The workaround is a bit strange. I created an NRPT entry under “Name Resolution Policy” in the Applocker policy and applied that policy to the win 10 client. After that, I removed this entry in the policy and NRPT still works. Get-dnsclientnrptpolicy now returns the entries. NRPT only specified where DNS queries are routed. You should always have a route to the networks where the DNS servers are located. Therefore, make sure that your clients are configured with routes that point all local subnets to the VPN interface. It appears that your customer was able to configure a transition tunnel because both IPv6 addresses of the tunnel endpoint respond to ICMP. If you cannot access internal resources, examine the client and verify that IPsec SECURITY associations have been configured. Otherwise, make sure that Windows Firewall is enabled (on the server and client!), and if this does not resolve the issue, you will need to investigate why the client is not authenticating correctly.
I hope this helps! I recently found that if you have NRPT DomainNameInformation rules in your device and user tunnels, they must match, otherwise you will get an NRPT corruption error in the EventLog (and also when running Get-DnsClientNRPTPolicy) and DNS record, we will only push the routes to the domain controllers, SCCM and RRAS/NPS along the device tunnel to restrict what can be called without user tunnel. Therefore, the network adapter on the RRAS server must have public DNS servers that can be made available to the client so that computers can continue to access Exchange/SharePoint when no user tunnel is deployed (our initial use case was simply to allow the first remote connection through a device tunnel). What I seem to have found today is that exceptions that don`t work are at least partially related to the “AutoTrigger” option under “DomainNameInformation”. If you have an automatic trigger true for a domain/suffix, the nrpt rules are added before the tunnel is opened and you do not seem to be able to make any exceptions. However, if you do not have an automatic trigger or if you are set to false, they will be added after the tunnel expires and the exceptions will work. The device tunnel does not support the use of the Name Resolution Policy (NRPT) table. The device tunnel does not support the force tunnel. docs.microsoft.com/en-us/windows-server/remote/remote-access/vpn/vpn-device-tunnel-config Hello Richard, I have the problem that when using NRPT, a “wpad” entry is automatically created in the NRPT table. There are also automatic entries for isatap and _ldap.
We work with a split tunnel and don`t want wpad to be solved through the VPN tunnel. The proxy setting on the client is automatic. If “wpad” is resolved, I cannot access the Internet with my browser. wpad is used internally in the local network. When I create an NRPT exclusion for “wpad” in the XML, I get an error message when I call Get-DnsClientNrptPolicy, but it`s worth noting that I can access the Internet with my browser. But all other NRPT inputs no longer work. Do you have any idea how I can prevent this? By the way; We are currently using 1809. Please define NRPT rules in Microsoft Endpoint Manager or in your custom XML, depending on how you configure your VPN Always On clients. Using DNS policies, you can create different DNS records for the same host name that resolve to internal and external IP addresses, and then use a policy to return the public IP address when your VPN clients make a name resolution request, but return private IP addresses for all other requests. 3) There are two rules out there: a regular rule for the company`s domain namespace and an exception rule for the NLS domain name (which points to its LOCAL address) Not quite.
Get-DnsClientNrptGlobal is the command to view global configuration rules, while Get-DnsClientNrptPolicy displays all the rules contained in the policy. Get-DnsClientNrptRule provides information about a single rule in the NRPT policy. I haven`t released anything yet, but I`m happy to provide sample code if you wish. Contact me directly and I will send you something. I`m using an Always On VPN device tunnel. We have a certain need to use shared DNS. Our configuration has our domain names and name servers. We have an exception for our external VPN gateway address. During the connection, the internal name resolution works correctly. All Active Directory services fail. When the VPN is connected, the domain name does not resolve to a domain controller. AD SRV records are available when queried directly.
An idea why the domain name would not be solved? We only have both rules when we list the table of rules. To be clear, the NRPT “solves” nothing. It only forwards name resolution queries based on the namespace to specific DNS servers. 🙂 That is, VRS records are fully submitted to the NRPT and are transmitted in accordance with the defined policy. I added myself to Direct Access AD, so DIrect Access is configured and unbalanced when I`m at wotk but can`t find these registry entries. We try to use the NPRT exclusion for the VOIP service, but instead of resolving external IP addresses, the user profile URLs are resolved in our internal DNS, which indicates that the NPRT rules are not working. We use NPRT device AND user tunnels that are only configured in the user tunnel. Is there a Powershell script to add bulk NRPT rules to the table in DA? Removing this entry from our table solved the problem and now when we disconnect from the VPN, the NRPT rules are unloaded from the client.
Addresses an issue with the Always On virtual private network (VPN) where Name Resolution Policy Table (NRPT) rules cannot be removed after disconnection. Hi Richard, do you have any tips for troubleshooting NRPT for Always ON, does NRPT work in the same way as direct access? If you use ProfileXML to set the NRPT rules and Get-DnsClientNrptPolicy = empty, but Get-DnsClientNrptRule = displays the NRPT rules configured via XML, you must delete this *KEY* not a *VALUE* in the key, but the key itself: HKLM:SoftwarePoliciesMicrosoftWindows NTDNSClientDnsPolicyConfig foreach ($n in $nrpt){ Remove-DnsClientNrptRule name $n.Name -PassThru -Force } Hmm, We do not see this behavior for AlwaysOn, Get-DnsClientNrptPolicy = Empty, Get-DnsClientNrptRule = Rules configured for NRPT on CSP.
