Hi everyone. I'm not very familiar with setting up networks and was hoping someone can give me some help here. I think I bit off more than I can chew by getting a managed switch (SODOLA SL-SWTGW215AS 5 Port 2.5G). My objective was to create an isolated network with the SODOLA 5 port switch where all the devices on the 5 port switch can communicate with each other and connect with the internet, but can't communicate with any other devices on the network. I wanted to know if I even need to do anything or if I need to make some changes in the configuration vlan section to accomplish this. Also, I just got a new NAS (QNAP TS464) which has 2 x 2.5G ethernet ports and wanted to take advantage of the throughput of the QNAP with this switch as well. So far, I haven't made any changes to the settings on both the NAS and the switch, I'm getting terrible transfer speeds. Any suggetions as to what I should be doing would be appreciated. I have attached a diagram of my network for reference. Thanks,
