To troubleshoot the NSX IPSec VPN service that has been reported down, you need to follow these steps:

Log in to the NSX Manager UI with admin credentials. The default URL is https://<nsx-manager-ip-address>.

Navigate to Networking > VPN > IPSec VPN and select the IPSec VPN session that is down. You can identify the session by its name, local endpoint, remote endpoint, and status.

Click Show IPSec Statistics and view the details of the IPSec VPN session failure. You can see the error message, the tunnel state, the IKE and ESP status, and the statistics of the traffic sent and received.

Compare the configuration details of the IPSec VPN session with the expected configuration as provided below. Check for any discrepancies or errors in the parameters such as local and remote endpoints, local and remote networks, IKE and ESP profiles, etc.

If you find any configuration errors, click Actions > Edit and modify the parameters accordingly. Click Save to apply the changes.

If you do not find any configuration errors, check the connectivity and firewall rules between the local and remote endpoints. You can use ping or traceroute commands from the NSX Edge CLI to test the connectivity. You can also use show service ipsec command to check the status of IPSec VPN service on the NSX Edge.

If you find any connectivity or firewall issues, resolve them by adjusting the network settings or firewall rules on the NSX Edge or the third-party device.

After resolving the issues, verify that the IPSec VPN session is up and running by refreshing the IPSec VPN page on the NSX Manager UI.You can also use show service ipsec sp and show service ipsec sa commands on the NSX Edge CLI to check the status of security policy and security association for the IPSec VPN session.

To create a custom QoS profile to prioritize the traffic on the phoenix-VLAN segment and limit the rate of ingress traffic, you need to follow these steps:

Log in to the NSX Manager UI with admin credentials. The default URL is https://<nsx-manager-ip-address>.

Navigate to Networking > Segments > Switching Profiles and click Add Switching Profile. Select QoS as the profile type.

Enter a name and an optional description for the QoS profile, such as phoenix-QoS.

In the Mode section, select Untrusted as the mode from the drop-down menu. This will allow you to set a custom DSCP value for the outbound IP header of the traffic on the segment.

In the Priority section, enter 46 as the DSCP value. This will mark the traffic with Expedited Forwarding (EF) per-hop behavior, which is typically used for high-priority applications such as voice or video.

In the Class of Service section, enter 5 as the CoS value. This will map the DSCP value to a CoS value that can be used by VLAN-based logical ports or physical switches to prioritize the traffic.

In the Ingress section, enter 1000000 as the Average Bandwidth in Kbps. This will limit the rate of inbound traffic from the VMs to the logical network to 1 Mbps.

Optionally, you can also configure Peak Bandwidth and Burst Size settings for the ingress traffic, which will allow some burst traffic above the average bandwidth limit for a short duration.

Click Save to create the QoS profile.

Navigate to Networking > Segments and select the phoenix-VLAN segment that you want to apply the QoS profile to.

Click Actions > Apply Profile and select phoenix-QoS as the switching profile that you want to apply to the segment.

Click Apply to apply the profile to the segment.

You have successfully created a custom QoS profile and applied it to the phoenix-VLAN segment.

To troubleshoot ICMP traffic and make any necessary changes to the Boston application security policy, you need to follow these steps:

Log in to the NSX Manager UI with admin credentials. The default URL is https://<nsx-manager-ip-address>.

Navigate to Security > Distributed Firewall and select the firewall policy that applies to the Boston application. For example, select Boston-web-Application.

Click Show IPSec Statistics and view the details of the firewall rule hits and logs. You can see which rules are matching the ICMP traffic and which actions are taken by the firewall.

If you find that the ICMP traffic is allowed by a rule that is not intended for it, you can edit the rule and change the action to Drop or Reject. You can also modify the source, destination, or service criteria of the rule to make it more specific or exclude the ICMP traffic.

If you find that the ICMP traffic is not matched by any rule, you can create a new rule and specify the action as Drop or Reject. You can also specify the source, destination, or service criteria of the rule to match only the ICMP traffic from the main console to the Boston web VMs.

After making the changes, click Publish to apply the firewall policy.

Verify that the ICMP traffic is blocked by pinging the Boston web VMs from the main console again. You should see a message saying ''Request timed out'' or ''Destination unreachable''.

To deploy a new instance of NSX-T into an environment with two isolated tenants, you need to follow these steps:

Log in to the NSX Manager UI with admin credentials. The default URL is https://<nsx-manager-ip-address>.
