Dear all
Started to play around with IPv6 with my Swiss provider (VTX, not yet
officially supporting IPv6) and HE.net IPv6 Tunnel.
IPv6 works, but not correctly, some web pages do not load at all or
never end to finish loading. I guess because some routing problem.
Looking at "ifconfig" I have 2 questions:
1) Why do vr0, vr1_vlan, pppoe2 and gif0 interfaces have the same
link-local address?
2) Why does ppoe2 have a an official IPv6 address (in
GUI/Status/Interfaces it displays as Gateway IPv6)
On the box, IPv6 is on
On WAN interface: IPv4 Config Type: PPPoE; IPv6 Config Type: None
With Config-Type=None I would expect no IPv6 configuration at all,
except an link-local address.
I already tried other IPv6 config types for WAN, but result is always
the same. I have not yet contacted the provider.
The multiple and for me weird distribution of link-local addresses is
probably my missing knowledge ....
But the IPv6 gateway on pppoe without having a routable IPv6 behind the
link is the problem! How can I prevent/delete that interface and routing
setting?
Setup:
provider <-> pppoe2 <-> vr1_vlan11 <-> WAN
pfsense <-> WAN <-> vr1_vlan11 <-> pppoe2 <-> provider (VTX)
pfsense <-> IPV6HE <-> gif0<-> WAN<-> tunnel-to-ipv6 (HE)
A very similar setup where WAN is a static address (private address/DMZ)
works without a problem. The problem is not the IPv6 tunnel setup.
