There is nothing theoretically stopping you from running two IP address ranges on the same Ethernet network. By that I mean that if your normal network was 192.168.0.0/24 and your VPN network was 172.16.0.0/24 then you could just connect both ports to the same network switch, and then another port of that switch would be connected to your cable running upstairs. You could decide which network to use on each device upstaris by manually setting the IP address within one range or the other. Bingo ... poor man's VLAN.
This would depend on a few things, 1) the ability to set the private IP network ranges on the Zhone for the two networks to be non-overlapping (independent), 2) the ability to turn off DHCP on one or both networks (nothing worse than duelling DHCP servers), and 3) that the Zhone is not being too smart for it's own good (in various ways) ...
If both the 'normal' network and the 'VPN' network are using the same fixed private network ranges then never be workable ...
Over to you, VQ engineers ... Any reason why we can't do this? I have done it before using multiple hardware gateways ... but I don't have access to a Zhone to test (yet).
I'm very curious, because I will need to do the same thing in my place ...
Checked with my colleagues, and this setup should be able to work. However, this setup is quite complex and more suited for the tech savy : )
I got my ViewQwest fibre connection activated yesterday and managed to get the VPN to my second floor of the house using the method suggested by Wibbly. Turned off DHCP for the VPN (so manually assigned the IP to the devices) via the WebGUI but left DHCP on for the regular internet connection as I only need the VPN for a couple of fixed devices.
I've been able to watch BBC iPlayer stuff, listen to music via Pandora, and connect to Netflix using the WDTV supplied by ViewQwest. Unfortunately, with the exception of Pandora, I'm not able to see these services on my WDTV Live Hub even after trying to rollback and upgrade firmware, so I guess I will have to switch between the two devices.
Issues:
A) I'm not able to see Hulu on the WDTV supplied by ViewQwest. Is there anyone else with the same problem?
B) Occasionally, my computer upstairs does not seem to connect to the VPN properly for extended periods of time (even though downstairs it's fine). Basically when I click on an URL the pages stay on loading forever. This problem does not happen with the non-VPN network range. Is there some sort of configuration I might have overlooked? I'm guessing there's some sort of internal conflict going on within the hardware. I've already turned off DHCP for the VPN so not sure what's wrong.
My set up:
Downstairs:
Zhone (VPN+regular) connected to router LAN port (router IP is 192.168.0.64)
Regular network range is 192.168.0.100-200; 255.255.255.0
VPN: 172.16.0.100-200; 255.255.255.0
Upstairs:
Two routers connected to each other through LAN ports. All computer upstairs are connected to the routers.
One of the routers upstairs is connected to the router downstairs through LAN ports (router IPs are 192.168.0.65 and 192.168.0.66)
