Hello. I'm facing this scenario. I have three PCs: A, B, and C. PCs A and B are connected within the same network. PCs B and C are also linked together. How can I reach PC A from PC C via PC B? EDIT: PC A and PC B belong to network 1, while PC B and PC C are in network 2. Therefore, PC A and PC C aren't on the same network. END OF EDIT Thank you for your guidance.

Assuming all devices are on the same network, PC A equals PC B, which in turn equals PC C. Thus PC A matches PC C. You could link them directly via VNC.

You're asking about a specific issue with VNC connections. Are you trying to connect remotely using VNC and seeing problems with PC A while PC B works? You might need to adjust network settings or ensure the correct VNC server is running on PC B.

Note that PC A and PC C operate on separate networks.

What does it mean PC B is in two networks?

I performed this using a VLAN on my switch.

It seems there are two ports on the device too. To keep the networks distinct yet connected, you’d need a router in between, or you could repurpose PC B as a router or purchase one.

What is an ACL? Your image helps clarify the setup. Normally, PC 1 connects to both PC 2 and PC 3. When you link from PC 3 to PC 1, which in turn links to PC 2, there should be a path for PC 2 to reach PC 3 via PC 1.

Connect Router 2 to Router 1 and configure a static route for the subnet PC3 uses from Router 2 to Router 1. If your switch supports SVIs (layer 3 capability), the process is simpler and you avoid additional steps.
