Troubleshooting cisco packet tracer

[niklasBF]

1. I can't get an IP from my dhcp(2) on my second laptop "Contractor"

2. I can't ping outside my lans to internet. we currently use RIP and i don't know which ip to add or if i have to configure something in the homerouter(nat)

3. How does it work with 2 dns. Do you just send the signal from 1 to the other?

Hello @niklasBF 

1/

Modify the IP on SVI 20 on CORE-03:

Configure IP as 192.168.20.254 255.255.255.0 ; .100 is the IP #2 pf your DHCP Server.

After that Laptop "contractor" have an IP address by DHCP:

2/

On Core 03 redistribute the defaut route under RIP process:

All routers will know the default route now from CORE-03 exit internet interface.

Perform NAT and you should be able to join Internet ressources

Inside traffic to Internet ?

You need to perform NAT....but core3 is a Switch and NAT capabilities is under SVI not interfaces....that's make complicated your configuration on Core3 I think. Possible to put a traditional router instead of Core3 ? 

Aftet that, NAT inside trafic with IP source coresponding to Router interface facing "Internet Router"....IP delivered by DHCP.
