Splitting Broadband into two LAN's

Hey everyone,




I've moved over to Sky so have a Sky Q Router and wondered what would be the best way of splitting my connection to provide two seperate LAN's that do NOT see each other.
The reason for this is to seperate my IOT gadgets, etc on one LAN and my private NAS, computers, etc on another.


Now I thought about using a ubiquiti security gateway that provides two ports and each would be a seprate LAN. This would go into my Sky router. (Yes I know it would be double NAT)
But this means I would then need two extra switches into those LAN ports to give me ports to connect to.


Is there another way via a VLAN switch that could go straight into the Sky router?
Then seperate ports belong to a different VLAN. Or would the switch not be able to do routing to the web (sky router)?


Your thoughts would be much appreciated.


Thankyou.

Re: Splitting Broadband into two LAN's

You will need an L3 switch and move routing/DHCP onto it.

VLAN interfaces and static routes to forward traffic from switch to router

Re: Splitting Broadband into two LAN's

I thought I may need a Layer3 switch. Thanks for your reply.


They are quite expensive so maybe the Security gateway and some cheap switches may be the plan for the moment.

Re: Splitting Broadband into two LAN's

If the IOT stuff is wireless can you use guest network for those?

Devices like Netgear GS108Tv2 - 8 port gigabit managed switch for £57 on Amazon.

Thanks tweetiepooh. Some are Wireless, some Ethernet so unfortunately a Guest Mode router wouldnt work.

Re: Splitting Broadband into two LAN's

Do you have to use the sky q router?

You could go down the used 2nd hand Juniper/netscreen device (or similar) and then an l2 switch and simply trunk the vlans across

Re: Splitting Broadband into two LAN's

USG will support the VLAN tagging and DHCP functions required for this use case but unless you can put the Sky CPE into modem only mode (which I am sure someone will confirm that you cannot) then I wouldn't bother with the extra bump in the road.

Re: Splitting Broadband into two LAN's

Thanks everyone.


You are right, the Sky equipment cant be put in to modem only mode.



The USG wouldnt have enough ports but an UBIQUITI Networks EdgeRouter would have suffiecient ports.
Im thinking Sky router, then the Edgrouter and then restricting ports/firewall rules for each port.

Re: Splitting Broadband into two LAN's

You should be able to a secondhand Cisco or Juniper small business L3 switch for around the ton mark.

There's an SG300-10 going on fleabay at the for 100 quid right now. IIRC that'll give you up to 8 DHCP pools so plenty enough to service your wired and wireless infrastructure.
