Separate the isolating machine from the rest of the network.
Separate the isolating machine from the rest of the network.
I have devices on both the top and bottom switches. I want everything to stay normal while keeping Server 1 active and connected via the router. I understand this might be a tricky setup, but could it work with the current arrangement? I’m happy to help if anyone can guide me. I tried assigning Server 1 and its connection on the bottom switch to a specific VLAN, but it still showed up behind the other switch. I assume visibility depends on the position relative to the switches, not just from one side. The physical layout limits what’s possible, though. Ideally, the rest of the network shouldn’t detect Server 1, and vice versa. The router doesn’t support VLANs, but the managed switches do.
You could always set SERVER 1's local firewall to block unwanted traffic. This would cover your entire local network subnet. The router's VLAN configuration might not function as intended if other devices remain visible. It could also be due to improperly configured interfacing policies. Another option is to connect all machines to a single small managed switch with VLAN support, or use a router/firewall such as a Sonicwall TZ270 that enables proper VLAN management and networking.
