I have a configuration in which I'm sharing my internet connection with a few others who are remote using STX links.
My topology is as follows:
RB2011UAS --Ethernet-- STX1 Client Mode --Nstream Wireless-- STX2 AP Mode --Nstream Wireless-- STX3 Client Mode
I have remote clients connected to both STX2 and STX3 using switches connected to the Ethernet ports of both STX2 and STX3. I'm using Nstream between the STX Radios in bridge mode. The RB2011UAS has the DHCP server on 192.168.89.x which provides the network access for the remote clients. The separate 192.168.88.x network is used for local clients on the RB2011UAS and the firewall does not allow traffic originating on the 89 subnet to terminate on the 88 subnet.
All this works as desired.
It turns out that the client location for STX3 is high on a hill and I want to install a HDHomeRun TV tuner at that location to bring broadcast TV back to the RB2011UAS 88.x LAN but wish to have the HDHomeRun tuner on the 88 subnet.
Question: If I place a RB750 (or a WRT54GS running DD-WRT) at the STX3 location, can I successfully configure this network to add a VLAN to the network so that the 89.x network continues to work as it does now (untagged LAN for clients at both STX2 and STX3) while transporting a VLAN over the Nstream links to the RB750 (or WRT54GS running DD-WRT) so that it can be broken out and connected to the HDHomeRun TV tuner?
If so, is there a pointer to how to configure the RB2011UAS and RB750 for a port that has both native LAN traffic and VLAN traffic?
