Syslog Integration With Fortigate Firewall
In this lab, we will configure Windows OS based Kiwi Syslog with Fortigate firewall. There are already some enterprise level solutions from Fortigate but this lab is prepared for those who wants to keep their external syslog server on Windows server. There are several syslog application, in this example we choose Kiwi syslog. Also you […]

GRE Tunnels between multiple sites
A GRE (Generic Routing Encapsulation) tunnel in Cisco is a method of encapsulating and tunneling network traffic over an IP network. It allows the creation of a virtual point-to-point link between two endpoints, typically routers or switches, across an existing network infrastructure. Here’s how it works: GRE tunnels are often used for various purposes, such […]
Multiple company-sites IPSEC connection with multiple VLANs
IPsec, short for Internet Protocol Security, is a suite of protocols used to ensure secure communication over IP networks. It provides security services at the IP layer by enabling encryption, authentication, and integrity checking of IP packets. IPsec can be used to establish secure VPN (Virtual Private Network) connections between remote networks or individual devices, […]
PfSense firewall + L3 Core switch configuration with VLANs
In this lab, we will create 3 vlans and connect our core switch to pfSense firewall with a transit network. Then we will configure our firewall with these vlan subnets. LAN related traffic will not hit the firewall, because SVIs (VLANgateways) will be created on L3 Core switch. All the necessary permissions between vlans will […]
Cisco ASA Transparent Internal Firewall Configuration
Cisco ASA (Adaptive Security Appliance) is a security device that provides firewall, VPN, and other security services for networks. It can operate in multiple modes, including Routed Mode and Transparent Mode. Let’s focus on Cisco ASA Transparent Mode. In Transparent Mode, the Cisco ASA firewall is inserted into a network without requiring any IP address […]
What is Netflow protocol? Deployment of Netflow server
NetFlow is a network protocol developed by Cisco that is used for network traffic monitoring and analysis. It allows network administrators to collect and view information about the traffic flowing through their network devices, such as routers and switches. A NetFlow server, sometimes referred to as a NetFlow collector or analyzer, is a system or […]
What is a DNS Server? How to setup on a network?
A DNS server, or Domain Name System server, is a crucial component of the internet infrastructure that helps translate human-readable domain names into IP addresses. Domain names are the familiar web addresses that people use to access websites, such as “www.barisyuksel.com.tr“. IP addresses, on the other hand, are numeric identifiers that computers and devices use […]
