I just received a brand new Cisco 3560G w/PoE switch
I configured 3 different VLANS were two of it are connected to a two different Lan ports onto a SonicWall TZ210 Firewall (same as tow different routers) .
I don´t know why but there are traffic passing from the vlans (something not desirable) and I am getting loopback message error at the router.
The PC´s located in each vlan received their Ip address from two differents DHCP Servers, but this is something that do not happen.
My problem is that the clients from VLAN 2 (e.g.) are receiving DHCP & DNS info from VLAN 1 servers.
