General Discussion / Re: Internet IPv6 Prefix Request from ISP won't work

« on: August 24, 2024, 08:19:31 pm »

Now only this question is open:

If I dial in PPPoE from the FW01 over the RT01, it is a tunnel like connection?
Or in other words is the Internet Traffic a Payload ofa frame-protocol? How that exacly works?

Cause u have with this setup the [PPPoE]-Interface at the OPNsense and not at the RT01.

So is the [WAN]-Interface itself Local or Public?

Thx.

Hey Dseven,

U r my hero    I got the the prefix /56!

You should see a route for it under System -> Routes -> Status...

I've expected see the prefix under Interfaces --> Overview , but there it isn't print.
Under routes I've found the requested prefix.

Wow, thats a bit weird and not intuitive by OPNsense, but ok, now I know it. Thx a lot.
Spend now the half day to fix this not existing problem...

Hey,

I think, cause ICMP is normally not really critical and dropped by driver / kernel, if there's a temporary micro-overflow in buffers. And this could happen by every hop, the ICMP passes.

This is the reason, why u in scripts do a connectivity check over ICMP never base on only a few packages rather than messurement over time.

I dont know, how exactlly implemented ICMP in your cards or the OPNsense, but maybe try to send ICMP with higher QoS Priority and compare results, if its critical. Never does it, but could a nice experiment.

EDIT:
A complete other direction of thinking:
It's possible the CPU has interrupts or micro-spikes.

General Discussion / Internet IPv6 Prefix Request from ISP won't work

« on: August 24, 2024, 06:30:51 pm »

Hello, Companions 

I have some problems to request a IPv6 Delegation Prefix from my ISP (o2 Germany, VDSL2, VLAN 7).

--------------------------------------

But first I show up my setup:

ME01 (Biological Working Drone, surely outdated and replaced by AI in future ;-)
[Experience] IT-Admin, but no expert at deeper level, especially BSD

RT01 (AVM fritz.box 7412 as Modem-Router)
[WAN] Only for DSL-Sync, PPPoE-Passthrough configured, so no IP
[LAN] Static 192.168.178.1/24
[WIFI] Deactivated

FW01 (OPNsense with 2x Realtek Consumer Cards)
[WAN] Static 192.168.178.2/24
[LAN] Static 192.168.0.1/24 --> (Beyond this are more, but not relevant)
[PPPOE0@OPT1@WAN] Dynamic from ISP

- I've configured on RT01 PPPoE-Passthrough and "forbid" the Dial-In, so that FW01 can use the PPPoE-Passthrough.
- I've established a PPPoE connection from FW01 sucessfully and get an IPv4 and IPv6 from ISP.

--------------------------------------
Now the problem:

I've set DHCPv6 in the PPPoE settings. I configured the following:
"Request prefix only"
"Send prefix hint"
"Prefix delegation size" to /56.

But I don't get any prefix in any size, the settings completly ignored.

If I configure this setup similar on the RT01 directly, it work, so I really can request prefixes up to /56.
But the OPNsense won't get any prefix.
I need a hint to solve this.

If u need more infos, tell me.

--------------------------------------
Than a second question:

If I dial in PPPoE from the FW01 over the RT01, it is a tunnel like connection?
Or in other words is the Internet Traffic a Payload ofa frame-protocol? How that exacly works?

Cause u have with this setup the [PPPoE]-Interface at the OPNsense and not at the RT01.

So is the [WAN]-Interface itself Local or Public?

Thx.
