I have a problem, that I cannot bring together working PAT and Port forwarding on a Cisco router. Here is my topology: Explanation to topology: Start connection sourced by 192.168.1.1 with destination port 1234 and destination ip address 192.168.1.2 and destination port 5678 out of f0/0. 1234 192.168.2.2

Starting from the following network topology: Internet ISP Cable Router Firewall Router rest of the network / multiple VLANs (port forwarding) | DMZ I had to expose two VLANs over the internet through VPN for two groups of users. what is the recommended way of achieving what I want to do?

Kentik Cloud users can now access the new Kentik Map for Google Cloud to automatically visualize detailed Google Cloud and hybrid cloud infrastructure topology. For example, an audit may be warranted if unexpected TCP traffic is flowing into a MariaDB instance but isn’t entering on port 3306.

In this blog, we will explore what static routes are, how they differ from dynamic routes, and how to configure them on routers like Cisco devices. This feature in networks predicts and stabilizes the topology. This characteristic makes them efficient for routers with limited processing capabilities.

This includes port, IP source, destination, port numbers, and other markings such as quality of service (QoS). That includes adding in high-value data such as threat feed and threat modeling, routing, topology, and other important networking information to model answers to difficult questions.

This configuration is known as a “split-tunnel” configuration and is set up by rules to exclude specific ports, protocols, or networks. If the VPN gateways cannot generate flow or Syslog with traffic, the next richest data comes from the edge routers or switches near the VPN devices. More advanced VPNs can do this by application type.
