With Catos LAN Firewall policy, you can configure rules for allowing or blocking LAN traffic directly on the Socket, without sending traffic to the POP. Figure 3 – LAN Firewall Policy When to use a LAN firewall policy There are several scenarios in which it could make sense to apply a LAN firewall policy.

NSGs use the source and destination address and/or port methodology which doesnt provide application layer visibility and logic. The outside subnet will be used for the appliances WAN interface, and inside for the LAN. It can also become overly complex to implement and troubleshoot as the environment increases in scale.

Rather, these firewalls are also used for securing WAN access, datacenter LAN segmentation and ensuring reliability and high availability to network traffic. Secure LAN Access SSE should secure VLAN traffic using access control and threat prevention engines. This must be done at the nearest SSE PoP to avoid latency.

This could mean the users are saturating the internet connectivity or that they’ve saturated the LAN (or maybe WAN). This configuration is known as a “split-tunnel” configuration and is set up by rules to exclude specific ports, protocols, or networks. More advanced VPNs can do this by application type.

Both packets and flows provide information about the source and destination IPs, ports, and protocols. Whether it’s tcpdump, Wireshark, or SPAN port, you’ll be able to get needle-in-the-haystack data with packet captures. The old saying about packet captures is that packets don’t lie!

In those settings, you might drop NPM appliances into major data centers, perhaps directly connected to router or switch span ports, or via a tap or packet broker from the likes of a Gigamon or Ixia. But cloud realities break that assumption. There are way more connectivity points that matter.

Organizations require a WAN that is capable of optimizing traffic flow between any two points not just to/from the enterprise LAN without compromising security. In addition, custom application definitions identify account-specific applications by port, IP address or domain.

Bad hardware (the switch or router port). Since we are focused on the cloud in this article, we find that SNMP is great for LANs and WANs, but we can’t use it to see inside devices within the cloud. Packet loss can be caused by a wide variety of factors, including: Bad cables (electrostatic interference). Overwhelmed router.
