Transfer runnning IPv6 config from FritzBox to pfSense

[Banane]

Hi everybody,

I´d like to change a FritzBox7360 I received from my ISP (Willy.Tel Hamburg, VDSL 100, Dual Stack) to my own pfSense-Firewall.
I must say I have absolutely no experience with IPv6 and want to take this little projekt as the beginning of getting some knowledge about it.

With pfSense Via PPPoE I receive a Ipv4-Address, but no IPv6-Address (The FritzBox just stays as a VDSL modem)

How do I have to configure the "IPv6 Configuration Type" on the WAN interface ?

Here are some informations I collected  so far:

Settings FritzBox Gui

- Connected right now -> Wilhelm.tel, IPv6-prefix : 2a02:2028:53d:a100::/56
- Support for IPv6 enabled [ x ]
- Always use a native IPv6 connection [ x ] 
- Derive global address from received prefix [ x ] 
- Use DHCPv6 Rapid Commit [ x ]

General Information from a ISP technican

- Allow IPv6 RA on the PPPoE device to get a default route
- On the PPPoE device use a DHCPv6 client which asks for a prefix (IA-PD)
- Announce the received prefix on the LAN for other devices

I really appreciate any single hint  :)

Kind Regards,
Christian

Your pfSense box is very likely a slave of the master Fritz. Talking pfSense-PPPoE directly to ISP is unlikely as  I know the 7360 in between. Browse my posts and maybe find something, test it and question more.

When you want pfSense-PPPoE in bridge to ISP, then you need to know the protocol to use for Interfaces: WAN(IPv6).

Hi,

that´s what i would like to find out  :). How do I have to configure IPV6 on the WAN interface?

I now switched the FritzBox to a Draytek Vigor 130 VDSL modem and set it to PPPoE-Passtrough.

Where do I have to set up the VLAN, at the Vigor 130 or at the pFsense firewall ?

At the moment i disabled the VLAN tagging at the VDSL modem and set it up for the WAN interface in pFsense.
I can connect via PPPoE and receive a Ipv4-address. Does this mean the VLAN is configured right ?

How do I have to set up IPv6 (DHCPv6/SLAAC).

Kind Regards,
Christian

Good move !

VLAN is at pfSense, Draytek-130 is absolutely pass-tru to ISP-node.

Why do you need VLAN(), because of separate ISP tagging of the Internet, Phone and TV ?

If you get an IPv6 that basically doesn't change, then go Static (+SLAAC if you wish) or DHCP6-server for your LAN.
Else you have to stick to Track-Interface for the LAN. This will do out-of-the-box. Issue /64 addressing i.e. 2a02:2028:xyzt:klmn:…../64

Prior and besides LAN-config, you need to know the connection protocol to ISP for WAN, probably with dhcp6(c)(PD).
Find out by experimentation or ask them the ISP.
