IPv6 forwarding from LAN problem

view story
linux-howto

http://forums.opensuse.org – I have an openSUSE 11.2 server configured as my firewall/server and ipv4 NAT router for my LAN. I have an ipv6 tunnel configured on it. All traffic to and from the server over ipv6 works just fine. All ipv4 traffic from the LAN gets masqueraded correctly. However, I cannot seem to route ipv6 traffic from my LAN. From the internal machine I can ping the firewall ipv6 address and my end of the sit tunnel. Any ipv6 traffic from the LAN seems to be getting dropped by SuSEfirewall2. The following appears in /var/log/firewall on the router: Jan 4 21:42:54 curly kernel: [32782.435572] SFW2-FWDint-DROP-DEFLT IN=eth0 OUT=sit1 SRC=2001:0470:1f07:0a4f:0000:0000:0000:0044 DST=2001:0770:0018:aa40:0000:0000:c101:c140 LEN=104 TC=0 HOPLIMIT=63 FLOWLBL=0 PROTO=ICMPv6 TYPE=128 CODE=0 ID=48408 SEQ=1 From this I can see that it appears to select the correct route from the internal network interface 'eth0' to the ipv6 tunnel 'sit1' but it is getting dropped. The following is what is happening on the internal client machine PING ftp.ipv6.heanet.ie(ftp.heanet.ie) 56 data bytes From 2001:470:1f07:a4f::1 icmp_seq=1 Destination unreachable: Address unreachable From 2001:470:1f07:a4f::1 icmp_seq=2 Destination unreachable: Address unreachable Does anyone have any suggestions?

Stories similar to IPv6 forwarding from LAN problem

I have assigned a stativ IPv6 address to eth2 interface and I am not able to ping it.

Here is the configuration setup done in /etc/sysconfig/networking/device/ifcfg-eh2

Intel Corporation 82546EB Gigabit Ethernet Controller (Copper)

DEVICE=eth2 BOOTPROTO=none HWADDR=00:11:0A:56:BB:68 ONBOOT=yes HOTPLUG=no DHCP_HOSTNAME=ipv6-http-ftp TYPE=Ethernet USERCTL=yes IPV6INIT=yes PEERDNS=no IPV6ADDR=2001

IPv6 static routes 24 weeks 3 days ago

I am looking to configure a few hosts with IPv6 on my network. The router (running CentOS 5) is configured with an Hurricane Electric (HE) tunnel which works fine on that host.

However, I would like to statically add a few additional hosts on the same LAN to have IPv6 through this tunnel.

IPv4 blocks IPv6 dns lookups 39 weeks 6 days ago

I'm using a IPv4 + IPv6 on a server (#1).

Sometimes the IPv4 address is mapped to another server (#2), so #1 isn't accessible via IPv4, but remains accessible via IPv6.

In this case IPv6 dns lookups won't work.

$ ping6 mirror.ipv6.hetzner.de unknown host

If I disable the IPv4 address everything works fine.

$ ping6 mirror.ipv6.hetzner.de PING mirror.ipv6.hetzner.de(2a01:4f8:0:a101::1:1) 56 da

I've a tunnel broker from he.net associate with a IPV6 /64 subnet

As a newby to ipv6, i've just discovered that its not reliable to only set a subdomain to a AAAA entry : because most of ISP will not be able to reach it

Considering i got 3 vm, each with ipv6 ip , i would like to know if there any way to set up my dns to handle that ?

I only got one IPV4 which is binded on the firewall

maybe t

I need to setup a PPPoE server for IPv6 on Ubuntu 11.10. I Followed one tutorial in Web. I am able to connect using IPV4.

Hello,

I have 2 Ubuntu machines one acting as IPv6 wireless router (running hostap and radvd on wlan0) and the other is connected to that router. the router wlan0 interface has the address 2001:db8:1:1::1/64 and the host has the address 2001:db8:1:1::2/64 on wlan0 which is connected to ap1 provided by the router.

hi guys, I have a problem about ipv6 on F17. My network support ipv6. I add Code: NETWORKING_IPV6=yes to /etc/sysconfig/network. I use Network-Manager to access network.

After I connect the system to network, I can go to ipv6 sites and use transmission to download via ipv6.

i'm trying to setup xen on a hetzner server, my dom0 has one ipv4 adress and a ipv6 subnet, i assigned every vm a different ipv6 address but i can't get ipv4 traffic to work.

i configured a network bridge br0 which has the ipv4 and a ipv6 ip from the server.

my dom0 interface:

auto eth0 iface eth0 inet manual auto br0 iface br0 inet static address 144.### broadcast 144.### netmask 2

I was looking for configuring Slackware to use ipv6 but all instruction I found speak about using an ipv6 tunnel that encapsulate ipv6 request into ipv4 packet and send them to an external router that extracts ipv6 request and sends a reply (or, at least, this is what I understood).

Is that necessary? Isn't there a way to configure a pure ipv6 system?
