Hi - I've been searching and trying various options with no luck. I'm starting to relaise that a little knowledge is a dangerous thing, but I love learning and solving problems, so if anyone has the inclination to help I'll be extremenly grateful!
I have two routers: a BT Home Hub 4 (very basic, ISP provided) and a Linksys EA6900 with Tomato 1.28 by Shibby. I also have a Netgear Smart Switch.
I initially replaced the BT router for the Tomato one to get all the benefits of VLANs, parental controls and better wifi. I set it up with three VLANs, 1. IoT, 2. Kids' devices, 3. Private/Secure - and I had the Netgear switch working with different ports on different subnets. All was fine until I realised BT internet TV wasn't working. I researched and the widely held view is that it just won't work with Tomato due to the nature of BT's multicast (people have tried with Tomato Multicast setting, IGMPproxy etc. to no avail).
So I've gone with both routers: BT as primary so the internet TV works, Tomato moved back as a secondary router linked LAN to LAN with the first VLAN on Tomato on the same subnet as the BT router. That subnet works for internet access through both routers, but I can't figure out if it's possible to get the other VLANs on Tomato to access internet through the BT router. Some details:
~~BT router~~
Gateway
IP address: 192.168.1.251
Subnet mask: 255.255.255.0
DHCP server: Enabled
IP Range: 192.168.34.50-99
~~TOMATO ROUTER~~
Basic > Network:
WAN Settings
Type: Disabled
Wireless Client Mode: Disabled
Router IP Addresses
br0 (LAN) 192.168.1.252/24
br1 (LAN1) 192.168.34.252/24
Gateway 192.168.1.251
LAN:
br0: 192.168.1.252 DHCP Disabled
br1: 192.168.34.252 DHCP Enabled 192.168.34.50 - 99
br2: 192.168.57.252 DHCP Enabled 192.168.57.50 - 99
Advanced > VLAN:
VLAN 1 VID 1 to br0 - ports 1 & 2 untagged
VLAN 3 VID 34 to br1 - port 3 untagged
VLAN 5 VID 57 to br2 - port 4 untagged
Advanced > Routing:
Mode: Router (but also tried Gateway)
I've tried some basic permutations in 'Advanced > LAN Access', but still no internet access for VLANs 3 & 5. I thought about static routing, though I can only do this on the Tomato router and if it's even possible I'm not really sure what the settings would need to be. I'd rather keep the routers LAN to LAN so I can have the IOT subnet across both routers for maximum coverage, but I am starting to think the only way will be to go LAN to WAN, then have one subnet on BT router, the other two on the Tomato router. If I do this, how would I connect the Netgear Switch so it can serve all three VLANs?
Any help very much appreciated.
Thanks,
Steve
