MT Serv has the following config
ether1 <vlan1> 10.100.0.1/24
MT_AP has the following config
Bridge1 (member ports: R52H,vlan1)
Ether1 <vlan1> 10.100.0.2/24
Client PC has a static IP assigned (to verify vlan connectivity), 10.100.0.50/24.
I can ping all devices on vlan1. I then created a PPPoE server on vlan1. I see the packets coming in through the R52H interface on MT_AP, but they're not making it to MT_Serv. It's like the PPPoE packets are not passing through the VLAN.
Just to further confirm the VLAN was working properly I setup a DHCP server on the vlan1 interface. Setup my client PC to see if it would receive a lease, and it does.
I'm confident the VLAN is setup and working properly, however the PPPoE-Discovery packets are not making it to the PPPoE server...
The MTU is set to 1500 bytes on each of the VLAN interfaces, the physical ethernet ports also have a 1500Bytes MTU. The PPPoE server is configured with 1480/1480 for MTU/MRU.
Do I need to raise the MTU on the physical ethernet interface to make room for the VLAN / PPPoE overhead... or is there something else I haven't done thats prohibiting the PPPoE discovery packets from being forwarded through the vlan?
