I have a Cisco 3560 Switch I am trying to configure out of the box for Branch location that is connected via a Hardware VPN/Firewall.
The firewall is assigned 10.30.0.1/16. The Switch is assigned 10.30.0.2/16. This network is the default VLAN1 (management).
I would now like to create a VLAN2 (for workstations) with the IP Address: 10.30.10.1/24 but when I do so I get an IP Overlap error. I am trying to breakdown my Class B, into Class C's.
What am I doing wrong?
