Related to my issues with using a DNS unblocker and Vodafone's transparent proxy, I think my best bet is to set up an old router I have and create a second network. The intention is to have my main router using Vodafone's DNS with everything except the connected to it either wired or wirelessly, then have the second router with the Getflix DNS in it and wire the Roku to that.

Before I rip into it I just want to make sure I have the right steps:

1. Log in to the second router, change its IP to 192.168.2.1
2. Keep DHCP on, assign the second router a static IP, put the Getflix DNS into the relevant fields
3. Connect the WAN port of the second router to a LAN port on the main router (this means the second router gets its WAN IP from the main router?)
4. Wire the Roku to the second router, connect the Chromecast to it

So this means the Roku will be using the Getflix DNS on the second router but getting a network connection via the main roouter? Tablets, phones, etc, can remain connected to the main router then connect to the second router wirelessly when necessary to access Netflix and so on?

My understanding is that this setup will create a double NAT but in my case it doesn't matter because it's only the Roku that will be connected full time to it?
