Hello everyone, in this video I am going to install mikrotik router os on hyper-v and after that I will be configure routerOS to provide internet access for clients by configuring dhcp server , create a nat rule , setup pptp vpn server. Ok lets start

1. Hardware Requirements:
   • MikroTik router device (such as a MikroTik RouterBOARD)
   • Ethernet cables
   • Computer with an Ethernet port
   • Power source for the router
2. Initial Setup:
   • Connect the MikroTik router to a power source and to your computer using an Ethernet cable. The router usually has a default IP address for the initial configuration, such as 192.168.88.1. Ensure that your computer is set to obtain an IP address automatically through DHCP.
3. Access the Router:
   • Open a web browser on your computer and enter the default IP address of the MikroTik router in the address bar (e.g., http://192.168.88.1).
   • You should see the MikroTik login page. The default username is “admin,” and there is no password by default. It is crucial to change the default password during the initial setup for security reasons.
4. Basic Configuration:
   • Once logged in, you can start configuring the router. Here are some basic configurations:
     • Set a strong password for the “admin” user.
     • Set the router’s hostname.
     • Configure the time zone.
     • Set the DNS servers.
5. LAN Configuration:
   • Configure the LAN (Local Area Network) settings, including the IP address and subnet mask for the router’s LAN interface.
   • You can create DHCP server pools to assign IP addresses to devices on your local network automatically.
6. WAN Configuration:
   • Configure the WAN (Wide Area Network) interface, which could be connected to your internet service provider (ISP). This often involves configuring the IP address, subnet mask, gateway, and DNS servers provided by your ISP.
   • Set up NAT (Network Address Translation) if you have multiple devices on your LAN and want them to share a single public IP address.
7. Firewall Configuration:
   • Create firewall rules to control incoming and outgoing traffic. MikroTik routers have a powerful firewall system that allows you to filter and control traffic based on various criteria.
8. Security and Access Control:
   • Configure access control lists (ACLs) to restrict or allow specific traffic.
   • Enable SSH or secure Winbox access for remote management and disable insecure services like Telnet.
9. Additional Features:
   • Depending on your needs, you can configure various additional features such as VPNs, VLANs, QoS (Quality of Service), routing protocols, and more.
10. Save and Backup Configuration:
    • After configuring your MikroTik router, make sure to save your configuration settings and create regular backups. This can be done through the router’s web interface.
11. Testing:
    • Test your network to ensure everything is working as expected. Check internet connectivity, LAN connectivity, and any specific services or features you’ve configured.
12. Documentation:
    • Keep thorough documentation of your MikroTik router’s configuration, including any changes you make over time. This will be helpful for troubleshooting and future reference.

Welcome to my channel , in this  video i will configure site to site vpn on Cisco ASA . i will show you the steps to set up a secure and reliable VPN connection between two Cisco Adaptive Security Appliances (ASAs).

Before we dive into the technical aspects, let’s take a moment to understand the importance of site-to-site VPNs in today’s interconnected world. As businesses expand globally, secure communication between different locations becomes paramount. Whether you’re connecting remote offices, data centers, or branch networks, a site-to-site VPN offers a robust solution to ensure data confidentiality, integrity, and availability.

Assumptions:

• You have physical or remote access to the Cisco ASA device.
• You have administrative access to the ASA via SSH, console cable, or ASDM (Adaptive Security Device Manager).

Step 1: Basic ASA Configuration

1. Connect to the ASA using SSH or the console cable.
2. Log in with your administrator credentials.

hostname ASA_NAME enable password YOUR_ENABLE_PASSWORD passwd YOUR_CONSOLE_PASSWORD interface GigabitEthernet0/0 nameif outside security-level 0 ip address YOUR_OUTSIDE_IP 255.255.255.0 no shutdown exit interface GigabitEthernet0/1 nameif inside security-level 100 ip address YOUR_INSIDE_IP 255.255.255.0 no shutdown exit route outside 0.0.0.0 0.0.0.0 YOUR_GATEWAY_IP 1

3. Replace ASA_NAME, YOUR_ENABLE_PASSWORD, YOUR_CONSOLE_PASSWORD, YOUR_OUTSIDE_IP, YOUR_INSIDE_IP, and YOUR_GATEWAY_IP with your specific values.

Step 2: Define ISAKMP Policy

1. Configure the ISAKMP (Internet Security Association and Key Management Protocol) policy to specify the encryption and authentication parameters for the VPN.

crypto isakmp policy 10 authentication pre-share encryption aes-256 hash sha group 2 lifetime 86400

Step 3: Create a Pre-shared Key

1. Define a pre-shared key that will be used to authenticate the remote VPN peer.

crypto isakmp key YOUR_PRESHARED_KEY address REMOTE_PEER_IP

Replace YOUR_PRESHARED_KEY with your chosen pre-shared key and REMOTE_PEER_IP with the IP address of the remote VPN peer.

Step 4: Create a Crypto Map

1. Create a crypto map that defines the remote peer’s IP, transform sets, and access control list (ACL) for traffic to be encrypted.

crypto map MY_CRYPTO_MAP 10 match address VPN_ACL crypto map MY_CRYPTO_MAP 10 set peer REMOTE_PEER_IP crypto map MY_CRYPTO_MAP 10 set transform-set MY_TRANSFORM_SET

Replace MY_CRYPTO_MAP, VPN_ACL, REMOTE_PEER_IP, and MY_TRANSFORM_SET with your desired values.

Step 5: Create an Access Control List (ACL)

1. Define an access control list (ACL) that identifies which traffic should be encrypted and sent over the VPN.

access-list VPN_ACL extended permit ip LOCAL_NETWORK SUBNET_MASK any

Replace LOCAL_NETWORK and SUBNET_MASK with your local network’s details.

Step 6: Apply Crypto Map to an Interface

1. Apply the crypto map to the ASA’s outside interface.

crypto map MY_CRYPTO_MAP interface outside

Step 7: Save the Configuration

1. Save the configuration changes.

write memory

Step 8: Verify the VPN

1. Check the VPN status using the following command:

show crypto isakmp sa show crypto ipsec sa

These commands will display information about the IKE and IPsec tunnels.

That’s it! You’ve configured a Site-to-Site VPN on a Cisco ASA. Remember to adjust the configuration to match your specific network topology and security requirements. Additionally, ensure that the remote peer’s configuration matches the parameters you’ve configured here for successful VPN establishment.
