The output below will be displayed on the core router.įrom the output above, we can see the source address 192.168.10.3 being translated to 1.1.1.2 as it heads out to destination 1.1.1.1 and on the second link we see the reverse process of 1.1.1.1 going to destination 1.1.1.2 before it gets directed to 192.168.10. 9.2.3.6 Packet Tracer Implementing Static and Dynamic NAT Packet Tracer Implementing Static and Dynamic NAT (Answer Version Optional Lab). After that, we run a ping from the computers on the LAN to the ISP router. To verify that NAT is working as it should, we turn on debug on the router, using the debug ip nat command. Where sub-interfaces are used for vlans, these sub-interfaces must be defined and used as the NAT inside interfaces. They use the physical interface instead of the sub-interfaces. This is where most people run into trouble. The final step is to define the inside and outside interfaces.

Each statement will reference corresponding access-list and NAT pool for that vlan. I am trying to get PC0 ping 8.8.8.8 through the network but it fails with 'Request timed out'. test - ping & do a show ip nat translation. I created a simple network in Cisco Packet Tracer for testing a simulated internet access with an ASA5506 and a 元 switch. Apply nat inside & nat outside to inside and outside interfaces. your private network you got your PC0 on.) Make a NAT statement - ip nat inside source list access-list name interface i.e. Router(config)#access-list 10 permit 192.168.10.0 0.0.0.255 Make an access list for networks you want to NAT (i.e. 11.2.3.7 Lab Configuring NAT Pool Overload and PAT 11.2.2.6 Lab Configuring Dynamic and Static NAT.

Packet Tracer : configuration de la NAT dynamique. Public IPs to be used in the NAT for multiple vlans For this demonstration, each vlan will be NATed to the public IP on the WAN interface of the router. We can NAT all three vlans to one public IP or to separate public IPs. Our objective in this lab is to configure NAT for the three vlans represented in the network topology. In this post, using a slightly modified version of the previous network topology, I will share with us on how to configure NAT for multiple vlans on a Cisco router.

Ip nat inside source static 192.168.20.254 my previous post, I shared with us on how to configure dhcp on a Cisco router with multiple vlans. Ip nat inside source list R2NAT pool R2POOL overload Configure the interfaces that will participate in NAT.Configure static NAT to map the local.pka server inside address to the second address from the 209.165.202.128/30 address space.Configure NAT with the ACL and NAT pool that you have created.All translated addresses must use this address as their outside address. The pool name you use must match this name exactly.

The pool should use the first address from the 209.165.202.128/30 address space. The name you use must match this name exactly.
