In our network we have untagged traffic on (say) subnet 100.100.100.0/24 and a VLAN200 on 10.10.200.10/24
I would like to configure a router so that:
All traffic passes between ports 1 and 2 untouched.
Traffic for a specific address on the native LAN (100.100.100.20) will be routed to port 3 to subnet 192.168.0.0/24 (src address 192.168.0.1)
Traffic for a specific address on the VLAN (10.10.200.20) should be untagged and routed to subnet 192.168.0.0/24 (src address 192.168.0.1)
Traffic from the private network to subnet 10.10.200.x/24 should be tagged and natted with address 10.10.200.20
Other traffic from the private subnet should be untagged and natted with src address 100.100.100.20
Way too complicated for my level of understanding.
Can you state where your internet ISP is on the diagram?
Where/What does port 1 connect too??
Where/What does port 2 connect too??
Where/What does port 3 connect too??
Lastly what requirements are you trying to fulfil? Describe what you need users to be able to do, WITHOUT talking about the configuration or hardware.
Thanks for thinking along.
The part I showed is actually part of a much larger bridged wifi network. Connection to the internet arrives at port 2 via a number of other switches and wifi relays, and the network continues from port 1 to other clients.
Port 3 connects to the private network of a client. It has a private address range (192.168.0.0/24) and is natted.
The client has a public IP address (100.100.100.20) and a private one (10.10.200.20)
I would like to be able to send tagged traffic from the client to IP addresses 10.10.200.x on VLAN200 and untagged to all other destinations.
