Thisis the reason why this type of NAT is not used very often – it requires one public IP address for each private IP address. Three steps are required to configure static NAT: 1. configure private/public IP address mapping using the ip nat inside source static PRIVATE_IP PUBLIC_IP command. 2. configure the router’s inside interface using Alternatively you can free download CCIE dumps PDF through Cisco questions. Refer to the exhibit. access-list 1 permit 0.0.0.255 ip nat inside source list 1 interface gigabitether net0/0 overload The inside and outside interfaces in the NAT configuration of this device have been correctly identified. ASA5506-X Basic Configuration Tutorial. The ASA 5506-X has a default configuration out-of-the-box. This default configuration has the following characteristics: Internal LAN: /24. Internal LAN can access the Internet. The WAN (outside) interface (GE1/1) is configured to receive IP address from DHCP. Wediscussed NAT Overloading above: Cisco IOS NAT configuration. Here, we will configure a Static NAT on Cisco IOS Routers. Static NAT is rather straight forward as it is a one to one NATing between IP addresses as against the NAT Overloading or the Dynamic NAT where the IP addresses from the inside are NATed to a pool of IPs.

We have some queries regarding this configuration. Private ip : 10.10.20.x/24. public IP: 43.88.64.x. 1> Nexus 9k will support or not for nat configuration. 2>Can we use hsrp virual IP for nating. Theconfiguration is almost the same as for dynamic NAT, but this time you specify the outside interface instead of a NAT pool. Router (config)# access list 1 permit 0.255.255.255.

Q7YBE. It is important to secure your Cisco devices by configuring and implementing username and password protection and assigning different Cisco privilege levels to control and restrict access to the CLI. Hence, protecting the devices from unauthorized access. In this article, we will discuss how to configure user accounts and how to associate them to the different Cisco privilege levels. Then, we’ll take a deep dive into their purposes and functions, as well as their importance in network security Level SecurityCisco IOS devices use privilege levels for more granular security and Role-Based Access Control RBAC in addition to usernames and passwords. There are 16 privilege levels of admins access, 0-15, on the Cisco router or switch that you can configure to provide customized access control. With 0 being the least privileged and 15 being the most privileged. These are three privilege levels the Cisco IOS uses by defaultLevel 0 – Zero-level access only allows five commands- logout, enable, disable, help and 1 – User-level access allows you to enter in User Exec mode that provides very limited read-only access to the 15 – Privilege level access allows you to enter in Privileged Exec mode and provides complete control over the By default, Line level security has a privilege level of 1 con, aux, and vty lines .To assign the specific privilege levels, we include the privilege number when indicating the username and password of the admin1 privilege 0 secret Study-CCNA1 Routerconfigusername admin2 privilege 15 secret Study-CCNA2 Routerconfigusername admin3 secret Study-CCNA3In this example, we assign user admin1 a privilege level of 0. Then, we assign user admin2 to privilege level 15, which is the highest level. For admin3, we did not specify any privilege level, but it will have a privilege level of 1 by try to verify the output of our configuration by logging in to each user. Enter the username and the corresponding password, starting with Access Verification Username admin1 Password Router>? Exec commands disable Turn off privileged commands enable Turn on privileged commands exit Exit from the EXEC help Description of the interactive help system logout Exit from the EXEC Router>Notice in the output above that the user admin1 is under User Exec mode and has only five commands- logout, enable, disable, help, and exit. Now, let’s log in as Access Verification Username admin2 Password Routershow privilege current privilege level is 15 RouterThe output above shows that user admin2 is currently in level 15, and we verified that by typing the show privilege’ command on the CLI. Notice also that we are in Privileged Exec mode. Lastly, let’s log in as Access Verification Username admin3 Password Router>show privilege current privilege level is 1 Router>When we logged in as admin3, we verified that it was in level 1 by typing the show privilege’ command on the CLI. Notice that we are in User Exec Levels 2-14You can increase the security of your network by configuring additional privileges from 2 to 14 and associating them to usernames to provide customized access control. This is suitable when you are designing role-based access control for different users and allowing only certain commands for them to execute. Hence, giving them restrictions to unnecessary commands and increasing the layers of security on the now assign privilege level 5 to a user. After that, we will configure privilege level 5 users to be in User Exec mode and allow them to use the show running-config’ admin4 privilege 5 secret Study-CCNA4 Routerconfigprivilege exec level 5 show running-configAll level 5 users now will be automatically accessing the User Exec mode and can now use the User Exec commands such as show running-config’ on the CLI. Let’s log in as user admin4 to verify Access Verification Username admin4 Password Routershow running-config Building configuration... Current configuration 57 bytes ! boot-start-marker boot-end-marker ! ! ! end RouterEnable Secret Command PrivilegeWe can also configure different privilege levels to passwords. Here, we will allow the enable secret’ command to access the Privileged Exec level. Use the enable secret level {level} {password}’ syntax as shown below. The command sets the enable secret password for privilege level secret level 5 Study-CCNA5We can verify our configuration as shown belowUser Access Verification Username admin5 Password Router>show running-config ^ % Invalid input detected at ^’ marker. Router>enable 5 Password R4show privilege Current privilege level is 5 Routershow running-config Building configuration... Current configuration 57 bytes ! boot-start-marker boot-end-marker ! ! ! end RouterIn our first attempt, notice in the example above that we do not have access to the show running-configuration’ command. That is because we are currently under privilege level 0. However, we can log in as a privilege level 5 user with the enable {privilege level}’ command, and from there, we can now access the show running-configuration’ our Free CCNA Study Guide PDF for complete notes on all the CCNA 200-301 exam topics in one recommend the Cisco CCNA Gold Bootcamp as your main CCNA training course. It’s the highest rated Cisco course online with an average rating of from over 30,000 public reviews and is the gold standard in CCNA training First of all, assuming that K router is ISP router, we need to remove nat configs from K router and add static routes on edge routers. there is also a duplicate IP address on serial interfaces. To make this NAT lab to work, we need NAT static entry on BB-S similarly what you have on DC router. Since you have same Private range on left and right sides, we need to hide those behind Nat. you can add on S router following entry ip nat inside source static you can test it using BB-K, an ISP router by pining Public IPs like or or newly added entry You cannot reach Private range from Internet, so you cannot ping any Normally and technically, to reach private web server from the Internet, routers will have static TCP NAT entries translating port 80 of Private IP to Public IP port 80. Example on BB-S has ip nat inside source static tcp 80 80 Regards, ML**Please Rate All Helpful Responses ** Ce tutoriel vous présente comment configurer un routeur Cisco. Cette configuration est celle de base, autrement dit, entre deux réseaux simplement. Livre complet sur la configuration du routeur Cisco Vous pouvez consulter la vidéo Ou le tutoriel écrit Mon réseau sera celui ci-dessous, donc d’un coté le réseau 1 en et de l’autre le réseau 2 en Ce test est réalisé sur Packet tracer car je n’avais pas de routeur Cisco physique sous la main mais les commandes sont les mêmes d’un routeur Cisco à l’autre. Pour le moment rien n’est configuré, même pas les deux PC, et pour communiquer entre les deux réseaux j’ai le routeur que je vais également devoir configurer. Dans un premier temps, je vais configurer le premier PC, je lui donne le nom de fafa-pc-1 Puis je configure son interface réseau. Je fais la même chose pour le second PC. Je tente un ping de la seconde machine sur la première, on ne sait jamais sur un malentendu. Comme prévu le ping échoue je ne peux pas communiquer avec l’autre réseau, normal le routeur n’est pas configuré. Le réseau ressemble à ceci pour le moment, les noms et interfaces réseaux des deux machines ont étés modifiés. Nous pouvons attaquer le routeur. Je me connecte sur le routeur, des informations m’attendent déjà. Je tape entrée pour que la console apparaisse, à partir de la je modifie le nom de routeur avec la commande hostname, je l’appelle rfafa. Je ne détaille pas les autres commandes qui permettent simplement de naviguer entre les modes du routeur. Maintenant je passe à la pratique, je vais configurer les mots de passes du routeur, par exemple quand je me connecte dessus. Je donne une bannière d’accueil à mon routeur. Ici se sera Bienvenue sur fafa-informatique » Je configure les deux interfaces réseaux du routeur, je fais bien attention à quel interface est sur quel réseau. Après chaque configuration d’interface je l’active avec la commande no shutdown. Mes interfaces sont prêtes. Je sauvegarde ma configuration, on ne sait jamais. Je vérifie que la configuration est bonne. La configuration du routeur apparaît, je peux la faire défiler avec entrée. Je vérifie les réseaux que connaît mon routeur. Je vérifie que les interfaces fonctionnent. Enfin, je vérifie en détail la configuration de mes interfaces. Je peux faire défiler les détail en appuyant sur entrée. En retournant sur mon réseau je constate immédiatement que les petits ronds sont désormais verts. Cela signifie que les connexions fonctionnent. Je vais néanmoins vérifier. Je ping depuis le PC fafa-pc-2 ayant pour IP vers l’interface réseau du routeur se situant dans son réseau. Le ping fonctionne parfaitement. Maintenant, je tente de pinger la machine sur l’autre réseau, ça fonctionne également. Nos deux réseaux peuvent donc communiquer. La première requête du ping n’est pas passée le temps qu’il trouve la route, mais toutes les requêtes passent. On le constate sur le deuxième ping. Ce tutoriel sur la configuration de base d’un routeur Cisco est maintenant terminé.
