Title: Need help for config PPPoE on opnsesne VM
Post by: thanhphpat on March 26, 2024, 09:03:22 AM
Hi all,
I have a situation in configuration PPPoE on opnsense.
Here is my diagram of network that its still working nomal:
ISP Moderm --- SW1 --- SW@ --- PROXMOX --- OPNSENSE Rounter

a. All sw hold 3 vlan (1 - 192.166.56.0/24, 2 - 172.16.100.0/24 and 3 - 192.0.2.0/24) Vlan 1 is managed by OPNSENSE, VLAN 2 is Guest and Vlan 3 is from ISP.
b. All vlan are trucking on one NIC on proxmox, (proxmox tag vlan 10)
c. Opnsense have tree interface created by proxmox. with vmbr 0 for WAN (192.168.56.0/24), vmbr0.10 for Lan (172.16.100.0/24) and last is for guest (192.0.2.0/24)

Everything worked  with ISP moderm dial up PPPoE.
Now I would like to using OPNsense dial up PPPoE but not work as bellow:
a. I config ISP to bridge mode (my ISP have vlan 11)
b. Config WAN: change from DHCP to PPPoE

So is there anythings that conflig in config, IMO i thing, should i change vlan 10 to vlan 11 and try to dial up PPPoE?
Please help me
Thanks

Create VLAN 11 on the WAN interface and use that one for PPPoE.

Last time, i created vlan 11 on WAN interface as you said, but not lucky, It seems not dial up PPPoE
so may be i misunderstood you.
1. Do I need to create vlan 11 and tag on all AP, and WAN interface of OPNSENSE
2. or on ISP moderm, should i let vlan tag as its was, or i turn off it.
Thank you many much

No, no, no ...

If your ISP says they want VLAN 11 for PPPoE that concerns only your WAN link. Don't create VLAN 11 on any internal interface.

If the modem already sets VLAN 11, of course your OPNsense must not do that. Only if the modem does not set any VLAN tag, your OPNsense must do that.

All of this depends on your modem, your ISP, and their configuration.
