![]() ![]() If not, ensure that the links are normal, interfaces are Up, and network configurations such as the routing configuration are correct. Run the ping command to check whether private and public network routes are reachable. Check whether private and public network routes are reachable.This configuration ensures that IKE negotiation can be triggered when no service traffic exists. Run the sa trigger-mode auto command in the ISAKMP IPSec policy view to set the IPSec SA triggering mode to automatic triggering. You can trigger IKE negotiation through a ping. The default IPSec SA triggering mode is traffic-based triggering, and the prerequisite for triggering IKE negotiation is that service traffic exists. SA trigger mode: Traffic-based //IPSec SA triggering mode IPSec SA local duration(traffic based): 1843200 kilobytes IPSec SA local duration(time based): 3600 seconds Run the display ipsec policy command to check the IPSec SA triggering mode.The following lists two IPSec fault trees: IPSec tunnel setup failure and abnormal IPSec services. Understanding the overall troubleshooting roadmap helps network administrators quickly locate and process faults. For complex faults, the network administrator can analyze triggering causes layer by layer based on the fault symptom and IPSec working principles to find the root cause. Such faults need to be processed based on the specific scenario.ĭuring routine maintenance or after receiving a fault report, a network administrator can find the troubleshooting guidance by referring to this figure. Usually, other IPSec faults are caused by incorrect feature configurations, such as interfaces, Access Control Lists (ACLs), routes, and network address translation (NAT). You can carry out in-depth analysis on the IKE negotiation process. IKE SA or IPSec SA negotiation failure is the core issue in IPSec faults. Data transmission stage: Services are abnormal (interrupted or of poor quality) after successful IPSec tunnel setup.Tunnel setup stage: An IKE SA or IPSec SA negotiation failure leads to an IPSec tunnel setup failure.Service triggering stage: Internet Key Exchange (IKE) negotiation is not triggered. ![]() You can also analyze faults according to the stage in which a fault occurs. So, I'll have to figure out how to get SEP to allow it.The preceding figure analyzes faults by symptom. I had already tried disabling the Network Threat Protection, but I decided to try a full uninstall. Currently when connected it says, "Some resources are not available" and the tray icon has the red X.Īny ideas? There's a lot of confusing information about DA out there, and nothing I've found directly addresses the problem I'm seeing.ĮDIT: Looks like Symantec Endpoint Protection was the culprit. I read an article about how ping works in DirectAccess and that it doesn't necessarily mean the IPsec tunnel is working, but I'd like the Connectivity Assistant to tell me everything is good. I'd like to resolve this so that the tools available report everything is good. As I said earlier, resources are accessible. Pinging the DA server from the client resolves to the IPv6 address of the internal adapter of the DA server.īoth the Direct Access Troubleshooter and Connectivity Assistant report issues, primarily because ping doesn't work. Firewall on the DirectAccess server has the appropriate firewall rules to allow ICMPv6 Echo Requests. General failure." It just says General failure). All I get for IPv6 ping is "General failure." (Note: not "Ping: transmit failed. It works, as I can access internal resources (iNet, file shares, RDP works both ways). Other than that, deployment was fairly easy. I had to make sure to have a machine certificate on the Windows 7 machine, as that's required. I followed a few guides and after some troubleshooting, I was able to get it working. Windows 7 Enterprise client - latest patches installed, as well as DirectAccess Connectivity Assistant 2.0, Teredo and 6to4 adapters disabled at a recommendation I read, as I'm using IPHTTPS since clients are behind NAT.Server 2012 R2 running DirectAccess - 2 NIC deploymented (1 internal, 1 DMZ), behind NAT firewall.I'm deploying a proof of concept for DirectAccess.
