Would someone be so kind as to check out the diagram attached and see the configuration file (also attached) and tell me if there is a problem with the configuration.
Basically I am trying to have an cisco 877 connect me to the Internet via ADSL, but have a Ubuntu laptop act as a DHCP server rather then have the 877 do DHCP.
The Ubuntu laptop is running DHCP correctly as when I attach a second laptop to the Ubuntu box with a crossover cable I pick up an IP address from the specified range.
However when I connect everything up as per the attached diagram I do not recive an IP address via DHCP.
I suspect I need to assign the Ethernet ports to VLAN1 but I an not sure about this, as when I had the 877 doing DHCP, once I attached something to one of the Ethernet ports it would pick up a IP address with no problem.
I am thinking that I need to create a second VLAN, assign the currnent VLAN1 configuration to this new VLAN and assign the 4 Ethernet ports to this new VLAN. But maybe I am off base or there is another way to achieve this.
Your insight as usual will be much appreciated
Best Regards & TIA
P.S. The Ubuntu laptop has the IP address 192.168.1.21/16
