Package: linux-image-2.6.26-2-vserver-686
Version: 2.6.26-15lenny2
Severity: important
I have a strange problem of IPv6 routing inside my vserver guests.
So, here is the network setup of the host :
eth0 has an IPv4 public address, it's my only NIC.
sixxs has an IPv6 address, it's a IPv6-in-IPv4 tunnel to sixxs.net. It has the
address : 2001:6f8:202:291::2/64
dummy0 has an IPv4 address : 192.168.0.250/24 and an IPv6 address :
2001:6f8:33c::1/64 which is a part of my /48 subnet. This subnet is routed to
2001:6f8:202:291::2. To do this, I've set :
net.ipv6.conf.default.forwarding=1
net.ipv6.conf.all.forwarding=1
in sysctl.conf
The network setup of one of my guests :
dummy0 : 192.168.0.1/24
2001:6f8:33c::3/64
root@nagios:~# ip -6 route show
2001:6f8:202:291::/64 via :: dev if19 metric 256 mtu 1280 advmss 1220
hoplimit 4294967295
2001:6f8:33c::/64 dev dummy0 metric 256 mtu 1500 advmss 1440 hoplimit
4294967295
fe80::/64 dev if2 metric 256 mtu 1500 advmss 1440 hoplimit 4294967295
fe80::/64 dev dummy0 metric 256 mtu 1500 advmss 1440 hoplimit 4294967295
fe80::/64 dev if7 metric 256 mtu 1500 advmss 1440 hoplimit 4294967295
fe80::/64 via :: dev if19 metric 256 mtu 1280 advmss 1220 hoplimit 4294967295
default via 2001:6f8:202:291::1 dev if19 metric 1024 mtu 1280 advmss 1220
hoplimit 4294967295
So, the services hosted on this guest are reachable from IPv6 hosts, this is OK.
But, when I initiate a connection from the guest to an external host in IPv6,
the source IP is 2001:6f8:202:291::2 and not 2001:6f8:33c::3. This is like NAT
in IPv6, something goes wrong...
I had a full working setup before upgrading in Lenny. I was on Etch with
util-vserver from backports.org (0.30.216~r2772-6~bpo40+1) and the following
kernel : http://files.si7v.fr/kernel/2.6.22.19-vserver-ipv6/ to have Vserver
IPv6 support.
Feel free to change my bug report if it concerns the package util-vserver. I
don't know if it's kernel related.
Best regards,
Pierre Tourbeaux

Yep, that's what I was looking for. Thanks again for your help!
