I have access to a Huawei ONT echolife hg8012H, input fiber optic, output 1GibE Ethernet, and a RF TV coaxial connector.
The working 3play setup is something like this:
[fiber optic] | | Huawai ONT | / \ | [RF connector]---> TV (Analog) | [1GigE Ethernet Port] | | 1GigE switch / \ | `-- FreeBSD (vlan 100) | | 3play Thomson TG784n router | / \__ [TelePhone] | [LAN (Natted) ports] | | | | PC1 PC2 PC3 PC4
This configuration help me to have 2 networks, one served by the Thomson TG784n router, and other for the FreeBSD server.
I could connect the FreeBSD server, because I knew the VLAN ID.
But suppose that I have only the ONT and the FreeBSD server, example:
[fiber optic] | | Huawai ONT | / \ | [RF connector]---> TV (Analog) | [1GigE Ethernet Port] | | FreeBSD
If I don't know anything about the VLAN ID's, I just know it works (service is available) but only after specifying the proper VLAN ID I would be available to get an IP via DHCP, how to find or discover, available ID's ?
Requesting an IP via DHCP without specifying an VLAN, doesn't work, I must specify a VLAN ID in order to get a routed IP.
The ONT web interface just displays info about the Fiberoptic and the status of the link, but nothing related to the VLAN's.
