Trying to setup IP addresses on my network

Solution 1:

Your diagram does not show IP addresses, so we can't tell how you have things configured. Here's one way you might do things:

  1. Interfaces e0/0, e0/1, e0/2 and e0/3 should all be in the same VLAN. They should not be L3 interfaces.
  2. The VLAN interface (L3) will have the address 192.168.233.1
  3. You need a default route on the switch with the next hop of the Firewall (port 2)
  4. The firewall needs a route to the 192.168.223.0/24 network with the next hop of the switch.
