Gns 3 connecting to kali client

General questions
1

Hi, so i am curently trying to give my kali linux and lubuntu machines internet within my gns3 virtual environment. I have the 2 clients connected to a hub, which is then connected to the VYOS router, which is then connected to the NAT node. i have configured the router and declared my eth0 address as DHCP. I’ve also configured it to set the internal address to my router address(192.168.1.254/24). I am successfully able to ping the internet within my router, but that connection does not translate over to the kali and lubuntu clients. i have configured the wired internet connection on both machines to the corresponding IP addresses but no luck.is there a step I am missing?

So, this is the diagram?

[PC_01] ------->  |         |
                  | switch  |  ---> VyOS Router -----> Nat router ---> Internet
[PC_02] ------->  |         |

Can you provide configuration?

Oh, all in gns3! In that case:

# Get IP addres from your NAT netowrk.
# I see no interface on the diagram, so I'll suppose:
# eth0 connected to NAT 
# eth1 connected to switch.

set interface ethernet eth0 address dhcp
set nat source rule 10 outbound-interface eth0
set nat source rule 10 translation address masquerade

set interface ethernet eth1 address 192.168.1.254/24

You can find relevant information and guidance on our docs:

Getting configuration:

show config
show config commands

Your host should be set up using ip 192.168.1.254 as the default gateway

Did you configure “system name-server ”?

What about a dhcp server?

Hello @elico
Configuration dhcp-server:

set service dhcp-server shared-network-name LAN subnet 192.168.1.0/24 default-router '192.168.1.254'
set service dhcp-server shared-network-name LAN subnet 192.168.1.0/24 range 1 start '192.168.1.10'
set service dhcp-server shared-network-name LAN subnet 192.168.1.0/24 range 1 stop '192.168.1.100'
set service dhcp-server shared-network-name LAN subnet 192.168.1.0/24 name-server '8.8.8.8'
