G.Fast Modem / IPv6 / Buy Questions

Installing and Using OpenWrt
1

I've switched my ISP to a smaller local one (Bavarian, Germany) providing FTTB and last mile (in House) through copper with G.fast. I already search through common sites/stores and found not many devices available supporting G.fast.Is there any modem you could recommend supporting G.fast or Router with G.fast and OpenWRT-Support? As far as I know the ISP-Hardware in the basement is from Huawei.

Currently (until I decide if I switch to a/which modem), I'm using the FritzBox 7582 provided from the ISP. I've disabled what's possible. So far I got most things working, except IPv6 as far as I understood how it should be: I'm getting a /56 from my ISP, sadly - I found a help-page (https://en.avm.de/service/knowledge-base/dok/FRITZ-Box-7590/1239_Setting-up-an-IPv6-subnet-in-the-FRITZ-Box/) from AVM - they only forward /62 to other routers if I understood this correct?

So I have to let DHCPv6 enabled (in FritzBox) and changed the following settings:

* Always assign ULA-Address
* Allow prefixes announced from other routers
* Preference of announcement: medium
* Publish DNSv6-Server via Router advertisement (RFC 5006) - enabled
* DHCPv6-Server enabled, assign DNS-Server, Prefix (IA_PD) and IPv6-Adresse (IA_NA)
  * Priority: 10

My Clients are perfectly getting an IPv6-Address in a subnetz of the provided /56 from the ISP. but the Router with OpenWRT (where the clients connect to) does not get any public IPv6 as expected. I set the following settings for br-lan (which is eth0 - as the devices does only have one port):

* Static IPv4
* Delegate IPv6 Prefixes = enabled
* IPv6 assignment length = 62
* IPv6 suffix: ::1:fe
* IPv6 preference: 25
* DHCPv6-Service is set to designated master
* RA/DHCPv6-Service and NDP-Proxy in relay-mode

Is this normal behavior? Can you recommend another solution where also the OpenWRT-Router behind the FritzBox gets a public v6? Lastly and I guess because this is because the OpenWRT-Device just acts as "relay" that's why no v6 devices will be shown in leases-v6 section with this configuration, correct?

Thanks for your support and helping out :slight_smile:

Hello npx,

have you found a satisfying solution or did you switch to a dedicated device to manage g.fast?
I'm also a customer of MNet and have the same configuration at home.
At the moment I'm just using the (not very stable) Fritzbox without openwrt, since the power demand of Fritzbox + power supply of the fttb splitter is already quiet high and I do not want to power an additional device.
The only thing I can think of, is buying a Draytek Vigor 166 g.fast modem and place it in front of the openwrt router. However the modem is quiet expensive, so I would be happy to find a cheaper solution.

Regarding your IPv6 configuration. I think you can just use the std. configuration on the Fritzbox. You will then receive a public prefix from the ISP and a suffix from the FB (or auto generated by the device using privacy extension). This address should be reachable from the Internet. What you have to do, is to open the firewall inside the fb (DMZ), since all external incoming traffic will be blocked otherwise. Since there is no NAT the device will then be exposed to the Internet.
Reachability of Ipv4 will probably be a problem because of the NAT. As far as I know it cannot be switched of, at least not with the branded firmware.

If you are brave enough, you can "hack" your FRITZ!Box to act as a modem and pass PPPoE through LAN4, so your OpenWRT router can use PPPoE itself. That's the way I'm using it here, not from MNet but from willytel in Hamburg with G.fast on FRITZ!Box 7583.

To do so, you have to backup your FB config first! Edit the config "live" with FBEditor and get it back in your FB from the FBEditor. Make sure to have a working backup of your config, if something goes wrong!

You have to check/edit two sections:
ar7cfg
nqos

I will post both of my FB configuration parts completely at the bottom, but take care, it will not fit for other providers! Willytel is using a very special VoIP configuration which I never got to work outside of my FB.

What does the trick? I will highlight the parts you have to check:

Here check the "tagtype" method in "ar7cfg":

        hsi_vlancfg {
                vlanencap = vlanencap_none;
                tagtype = vlantagtype_customer;
                vlanid = 0;
                vlanprio = 0;
                tos = 0;
        }

Here compare the vccs config, maybe "dslencap_pppoe" is a better choice if you don't have your VoIP running on the FB. Willytel uses here "dslencap_mixed" to use "dslencap_pppoe" for "internet" and "dslencap_ether" for "voip" for the two "dslifaces", if you only need one, then mixed should be unnecessary.

        vccs {
                VPI = 1;
                VCI = 32;
                traffic_class = atm_traffic_class_UBR;
                pcr = 0;
                scr = 0;
                priority = 0;
                dsl_encap = dslencap_mixed;
                ipbridgeing = no;
                ipbridgeing_igmp = no;
                pppoeforwarding = no;
                connections = "internet", "voip";
        }

Here check the dsl_encap value in "ar7cfg" and compare! Maybe your config is identical...

        dslifaces {
                enabled = no;
                name = "internet";
                weight = 50;
                dsl_encap = dslencap_pppoe;
                dslinterfacename = "dsl";

Here check and/or add the "bridges" section and set correct vlan id for MNet in nqos:

        bridges {
                enabled = yes;
                name = "bridge1_wt";
                ident = "vcc:0";
                vlancfg {
                        vlanencap = vlanencap_fixed_prio;
                        tagtype = vlantagtype_customer;
                        vlanid = 1002;
                        vlanprio = 0;
                        tos = 0;
                }
                disable_igmp_fwd = no;
                with_pppoe_bridging = yes;
        }

Next check the "classifiers" and output the above defined bridge to LAN4 in nqos:

        classifiers {
                enabled = yes;
                name = "wt_bridge1";
                type = qos_cfg_hidden;
                iface = qos_lan;
                rule = "ethport 4";
                result {
                        tos = -1;
                        vlan_prio = -1;
                        queueref = "realtime";
                        bridgeref = "bridge1_wt";
                }
        }

There are two more bridges defined in the config, but they are disabled! Bridge 2 is for LAN3 output and bridge 3 is for LAN2 output.

That should do the trick, then assign an IPv4 from your local subnet to your FB and connect LAN1 to any LAN port of your OpenWRT router, so you can access the webinterface of your FB to check DSL section for G.fast status etc., make sure to disabled all unneeded options (wifi, dhcp, etc.)

Connect LAN4 of your FB to the WAN port of your OpenWRT router and configure your PPPoE connection inside of OpenWRT with your DSL credentials form MNet, voilá!
