I have a rather basic need which I seem to be missing a key step in order to get this working. I have two subnets connected to a single 2708 switch. Within those subnets certain IP's or Ports must be able to talk while blocking traffic on the others. There is a locally attached server with four NICs, teamed into 2 Teams, one on each subnet. There is also a locally attached PC that both subnets must see which has only a single NIC and IP. I had VLANS setup but this was blocking access to the locally attached PC (Scanner) so I blew that setup away in order to get things in production. We can't leave it this way as we do need to block the two subnets if for no other reason than to block DHCP request crossing subnets and screwing everything up.
Network 1 - 192.168.0.x/24
Network 2 - 192.168.1.x/24
Port 1: Server Team 1 – 192.168.0.20
Port 2: Server Team 1 – 192.168.0.20
Port 3: SCANNER – 192.168.0.21 (locally attached PC)
Port 4: Server Team 2 – 192.168.1.20
Port 5: Server Team 2 – 192.168.1.20
Port 6: Uplink – 192.168.0.x
Port 7: Uplink – 192.168.1.x
Port 8: Uplink – 192.168.1.x
Both networks MUST be able to see the server and the PC(SCANNER). The Scanner is the problem as this was tossed at me during deployment and we CANNOT make changes to this PC such as adding another NIC to it which would make this super simple.
So using VLANS can you step me through this. My thinking is to go back to my two VLAN setup then just put Port 3 (SCANNER PC) into both Subnets. Yes? Trunking by term isn't in this switch so is it automatically tunked by being in both VLANS? Tagging should be set as how? I have little to no control of subnet 192.168.0.x/24, this is a separate office. On my side, 192.168.1.1/24 is a Dell 2848.
