I’m a bit confused …where did you set the ip address 192.168.194.10/24 VLAN 1, and 192.168.20.10/24 VLAN 2 ? (seems , but maybe I’m wrong , on interface vlan of the catalyst … 🙂 🙂 ) The vlans were created before adding zeroshell in your network ? I suppose that you already have some hosts in the 192.168.194.0/24 network , and their default gateway( as well as their dhcp server) is 192.168.194.1, … who are dhcp server and default gateway for the hosts members of vlan2 ? ( As far I know , on zeroshell machine is not possible implement something like the cisco command “ip helper address” ). But overall , how would you like configure your network ?
