Hi,
see these connections:
Currently, I'm using the top setup:
- Fritzbox, which connects to the internet via integrated DSL-Modem, acts as upstream-router for Openwrt.
- All interfaces of the Openwrt-device are member of br-lan with enabled VLAN-awarness.
- Although you cannot configure VLANs on Fritzbox, the Fritzbox-switch is also VLAN-aware, I mean it correctly transfers the VLAN-tags over the Fritzbox-interfaces.
- All open-ended lines in the above diagram represent network-members connected to the switch. If they use the untagged network, they are member of Fritzbox's LAN which is WAN of Openwrt.
All devices which use a specific VLAN are members of the corresponding Openwrt's-VLAN-network. - Due to routing-limitations, I want to get rid of this setup.
Thus, I want to change my infrastructure to the lower setup.
These circumstances are in place:
- I cannot use my Fritzbox 7490 as PPPoE-modem because this would conflict with VoIP/DECT-features I need on Fritzbox 7490.
- Thus, I implement another Fritzbox which acts only as PPPoE-modem for OpenWRT (and, if possible, as LAN-switch)
- Fritzbox 7490 shall act as member/IP-Client of a OpenWRT-LAN => VoIP-feature of Fritzbox 7490 will keep on working with this setup.
- Due to patching-limitations, I need the cabling as shown in the diagram.
With this setup, Openwrt would know his official IP-adress(es) provided by my provider and I would get rid of the currently routing-issues.
After much explanations, here are my questions:
- Is it possible to use PPPoE running through one or (in my case) muliple/two switches?
- Is it possible to run PPPoE as well as untagged LAN and tagged LAN over the one switch-uplink-connection of Openwrt?
If yes, what is the necessary bridge-/interface-setup?
Regards
Alex
p.s.
I know that this wiring is very unconventional.
