Destination Host Unreachable

beginner1
Beginner
Beginner

I'm a beginner in networking and Cisco packet tracer.

I'm currently working on a wireless LAN configuration network(.pkt file attached below.)

I've done the basic configurations.

When I ping PC2 from PC0/PC1, the message- "Destination host unreachable" appears.

What am I missing out?

Please help.

Thanks in advance.

Hi @beginner1,

 

That device, being a border router, has the NAT configured by default, so from external networks (supposedly from the internet) you will not be able to access the devices of a private network.

 

Unfortunately, PacketTracer has limited settings for that device, so you can not change those settings.

Hi @beginner1,

 

As @luis_cordova said, that router has a NAT preconfigure, I've tried to disable it but I couldn't, Instead of that, use an Access Point to access to your wireless devices.

 

I've donde the configuration on your file that I attached, PC2 has a static IP but if you want from DHCP, you can configure it in the switch.

You're not doing anything wrong. Looks like it a bug within Packet tracer. If you place PC on vlan 88, it works just fine. It's a bug with the wifi device they're using.

What is the solution then? please help me. I need to execute this in my college exam.

Can you please provide me with an alternate solution? 

Hi @Beginner,

 

Can you change the topology? If so, replace the wireless router with an accesspoint. Then, you will not have the separation of networks with Nat that the wireless router does.

Okay. Will try that. Thank you.

Hello,

 

are you talking about any Class A and B address (as in the link below), or private space addressing (10.0.0.0/8 and 172.16.0.0/12) ?

I'm referring to use of any Class A and B address as given in the link.

Look at the Private address space for reference : (RFC1918)
