Gold Plus – PPPoE + DHCP on same WAN port and same VLAN for Vodafone IPTV?

Hi,

I'm using a Firewalla Gold Plus as my main router on Vodafone Ireland FTTH, replacing the Vodafone Gigabox.

Internet works correctly using:

• WAN: Port 4

• VLAN: 10

• Connection: PPPoE

• Speed: ~986 Mbps down / 113 Mbps up

The problem is Vodafone TV Play Live TV.

Netflix, Emby, catch-up TV and even restarting a currently-live programme all work. However, selecting the actual live stream fails with:

"Live TV requires a stable internet connection – SAV1836"

I've already tried:

• IGMP Proxy enabled on the PPPoE WAN

• Emergency Access for the Vodafone TV box

• Vodafone TV over both Wi-Fi and the LAN/Deco network

None fixed Live TV.

From Vodafone Ireland information and reports from people using third-party routers, it appears the Gigabox creates two logical WAN interfaces on VLAN 10:

Port 4 / VLAN 10
├── PPPoE → Internet
└── DHCP/IPoE → IPTV/voice + IGMP/multicast

I therefore tried creating a second WAN in Firewalla:

• Port 4

• DHCP

• VLAN 10

• IGMP Proxy enabled

However, Firewalla App warns:

"Network Vodafone TV, FTTH should not be using the same VLAN ID: 10"

I have not saved this configuration because I don't want to disrupt the working PPPoE WAN.

I know Firewalla supports PPPoE + DHCP WAN interfaces on the same physical port when they use different VLAN IDs.

My question is specifically:

Can Gold Plus run PPPoE and DHCP/IPoE simultaneously on the same physical WAN port AND the same VLAN ID?

i.e.

Port 4
└── VLAN 10
    ├── PPPoE Internet
    └── DHCP IPTV

If this isn't supported through the normal Network Manager, is there a recommended Firewalla configuration for ISPs that use this arrangement?

Thanks.
