Thank you for your question. VPN looks OK, but I would try one thing. Under phase1-interface enable net-device and retest. The debug flow is missing something, not sure if it is trimmed. Ideal would be if you would have debug flow when session is established (before ping starts), usually that says the most useful info.
Meraki Firewall ip flow start and ip flow end [closed]
When you deploy a VM, Azure applies several default security rules to the VM that allow or deny traffic to or from the VM. You might override Azure's default rules, or create additional rules. At some point, a VM may become unable to communicate with other resources, because of a security rule. The IP flow verify capability enables you to specify a source and destination IPv4 address, port, protocol (TCP or UDP), and traffic direction (inbound or outbound). IP flow verify then tests the communication and informs you if the connection succeeds or fails. If the connection fails, IP flow verify tells you which security rule allowed or denied the communication, so that you can resolve the problem. Learn more about IP flow verify by completing the Diagnose a virtual machine network traffic filter problem tutorial.
Network security groups (NSG) allow or deny inbound or outbound traffic to a network interface in a VM. The NSG flow log capability allows you to log the source and destination IP address, port, protocol, and whether traffic was allowed or denied by an NSG. You can analyze logs using a variety of tools, such as Power BI and the traffic analytics capability. Traffic analytics provides rich visualizations of data written to NSG flow logs. The following picture shows some of the information and visualizations that traffic analytics presents from NSG flow log data:
The Cisco Meraki - Flows Allowed and Rejected dashboard provides a high-level view of the geographic locations and outlier graphs for allowed and denied traffic. Panels also show allowed and denied insecure traffic by protocol, allowed insecure traffic by application and host, allowed network activity on unencrypted ports, and a graph of flows by pattern.
Used to collect information about your network IP traffic and to monitor network traffic activity, NetFlow generates insights into application flows. By implementing a high-quality network performance monitor with a NetFlow reporting tool, you can troubleshoot network issues with a high level of specificity. For larger businesses with large IT departments, the information gleaned from NetFlow analysis can be used to facilitate more accurate capacity planning and decisions about how to best allocate network resources.
NetFlow works by interacting with IP flows, or sequences of packets connecting a server with a destination. Each packet that makes it through the router or switch is examined for certain IP packet attributes, which are then used as packet identifiers to determine whether a packet is unique or similar enough to other packets to be grouped with them.
NetFlow gathers all the data pulled from IP traffic leaving the device, inspects all the packets, and consolidates them into flows based on particular areas. Except for layer 3 protocols and router/switch interface, packets meeting all seven of the criteria above are grouped together. After their bytes and packets are tallied up, these compartmentalized flows are exported to a NetFlow collector.
NTA works by combining flow data and Cisco Class-Based Quality of Service (CBQoS) data with the performance data gleaned from NPM. NTA then processes and breaks down the data, to be put into interactive graphs to offer a comprehensive view of your traffic history.
I include Paessler PRTG Network Monitor on a lot of my lists because of the comprehensive nature of its network monitoring capabilities. PRTG has several use cases, including NetFlow monitoring, and it supports all the major flow protocols and more. You can only monitor a single site using the web application. If you want to monitor multiple sites or devices, you have to use the enterprise app on Windows.
Another NetFlow monitoring open source tool, ntopng is a traffic analysis solution that captures packets to monitor flow data. To get the data, it relies on an open-source NetFlow collector called nProbe.
I'm having an issue maybe someone can help me out with, I am trying to parse Meraki flows messages which look like this: gist.github.com flows1 1542054623.620528045 WA_KIR_MX65W flows src=10.130.1.84 dst=10.158.27.1 protocol=udp sport=54873 dport=161 pattern: allow all1 1542054626.601322601 WA_KIR_MX65W flows src=10.130.1.84 dst=10.158.27.5 protocol=udp sport=56930 dport=161 pattern: allow all1 1542054649.514505350 WA_KIR_MX65W flows src=10.130.1.84 dst=10.158.27.5 protocol=udp sport=65303 dport=161 pattern: allow all1 1542054649.495042529 WA_KIR_MX65W flows src=10.130.1.84 dst=10.158.27.5 protocol=udp sport=65305 dport=161 pattern: allow all1 1542054657.813423746 WA_KIR_MX65W flows src=10.130.1.84 dst=10.158.27.1 protocol=udp sport=60730 dport=161 pattern: allow all

Breaks up long-lived flows into 1-minute fragments. You can choose any number of minutes between 1 and 60. If you leave it at the default of 30 minutes your traffic reports will have spikes. It is important to set this value to 1 minute.
To workaround the issue, download and copy the meraki-cloud-controller-mib.MIB to C:\Program Files (x86)\PRTG Network Monitor\MIB on your core server and restart the Core Server before performing the auto-discovery.
Here's an example of the various configuration options available in the snmp-base.yaml file used by the ktranslate docker image to poll for SNMP and flow data devices. You can also see a heavily-commented sample in the KTranslate repository on GitHub.css-1p7qkn8margin-left:0.25rem;position:relative;top:-1px;.css-1vugbg2fill:none;stroke:currentColor;stroke-width:2;stroke-linecap:round;stroke-linejoin:round;margin-left:0.25rem;position:relative;top:-1px;.css-1yhl729width:1em;height:1em;fill:none;stroke:currentColor;stroke-width:2;stroke-linecap:round;stroke-linejoin:round;margin-left:0.25rem;position:relative;top:-1px;.
This will generate a Flow Device entity which will only have telemetry in the KFlow event namespace. Alternatively, collecting flow telemetry from a device that is in your configuration file as an SNMP device will add decoration of the KFlow data to the pre-existing entity, such as a Router or Firewall.
You can use the ping_only attribute in replacement of the flow_only attribute if you would like to collect RTT metrics from a flow device. If both ping_only and flow_only are true, the device will be treated as a flow_only device.
By default, flow telemetry is mapped to known applications based on evaluation of the layer 4 port in use on a specific flow conversation. If needed, you can override the default mapping by providing a YAML file during Docker runtime to the -application_map flag. This will allow you to specify application names based on ports you identify.
By default, flow data containers will collect and process every flow packet they receive. If needed, you can add an inclusion filter to the -nf.source flag that will ignore all traffic not matching the filter you provide.
Steering traffic flow and Log message: With on-prem proxy, the Netskope Client monitors for HTTP CONNECT requests. It checks for the domain name in these requests against the managed domain list. If the name matches then it will reconstruct the TCP SYN packet and send it through the Netskope Tunnel and at the same time it will send TCP RST to on-prem proxy, and it will take control of that connection. After the TCP 3-way handshake with Netskope proxy, it sends the HTTP CONNECT request and the flow continues with Netskope proxy. Since TCP flow will be with destination IP of on-prem proxy when Netskope Client logs the message, it will show destination IP as on-prem Proxy and the domain name will be the managed domain.

Mail flow rules are similar to the Inbox rules that are available in Outlook and Outlook on the web. The main difference is mail flow rules take action on messages while they're in transit, and not after the message is delivered to the mailbox. Mail flow rules contain a richer set of conditions, exceptions, and actions, which provides you with the flexibility to implement many types of messaging policies.
All messages that flow through your organization are evaluated against the enabled mail flow rules in your organization. Rules are processed in the order listed on the Mail flow > Rules page in EAC, or based on the corresponding Priority parameter value in the PowerShell.
Each rule also offers the option of stopping processing more rules when the rule is matched. This setting is important for messages that match the conditions in multiple mail flow rules (which rule do you want applied to the message? All? Just one?). 2ff7e9595c
