(If you use squid with tproxy, you will see the public ipv6 address of the client in the logs of the webserver) If all that you want to do is running some application as unprivileged user listening on port 80, you can also grant your application to bind on ports &lt; 1024 <div class="code">sudo setcap cap_net_bind_service+ep /path/to/your/app</div> then, your &quot;/path/to/your/app&quot; will be allowed to bind on ports lower than 80, even if you do not run it as root. </description> <pubDate>Mon, 29 Apr 2013 20:22:04 +0000</pubDate> <guid>https://www.sixxs.net/forum/?msg=devel-9258890-9285546&from=rss</guid> <author>MSK12-SIXXS@whois.sixxs.net (Michael Saxl)</author> </item> <item> <title>Preconditions for TPROXY within ip6tables</title> <link>https://www.sixxs.net/forum/?msg=devel-9258890&from=rss</link> <comments>https://www.sixxs.net/forum/?msg=devel-9258890&from=rss</comments> <description>Hi all,I try to use TPROXY to forward a port to another, but it is simly not working. If all ip6tables chains are empty (I know, it's a security risk, it's only for testing on private network), and I make the following: <div class="code">ip6tables -t mangle -A PREROUTING -i eth0 -p tcp --dport 80 -j TPROXY --on-port 8080</div> I assume accessing port 80 will be forwarded to an application listening to port 8080, but there is no traffic. I've done:- modprobe xt_TPROXY- echo 1 &gt; /proc/sys/net/ipv6/conf/all/forwarding- tried in new Debian Wheezy and in Ubuntu 12.04 LTS What id I forgot?

I managed to get NUD enabled in my tunnel and had a chance to get a look at the packets so now I understand. My mistake were that I though it would not be possible to send a Neighbor Advertisements in response to a solicitation since there would not be any link <u>layer</u> (MAC) address associated with the inner IP of the tunnel. I realized that it is possible to send &quot;empty&quot; Neighbor Advertisments, as response to a Neighbor Solicitations. These advertisements do no contain any information about the link <u>layer</u> address (MAC address) - perfect for a tunnel encapsulated packet. </description> <pubDate>Thu, 25 Oct 2012 14:25:53 +0000</pubDate> <guid>https://www.sixxs.net/forum/?msg=devel-8081558-8081802-8094238&from=rss</guid> <author>DHC8-SIXXS@whois.sixxs.net (David Henriksson)</author> </item> <item> <title>Neighbor Unreachability Detection in 6in4 Tunnels</title> <link>https://www.sixxs.net/forum/?msg=devel-8081558-8081802&from=rss</link> <comments>https://www.sixxs.net/forum/?msg=devel-8081558-8081802&from=rss</comments> <description>There is a link-local address.

What puzzles me is section 3.8 Neighbor Discovery over Tunnels. How are Neighbor Unreachability Detection probes sent and replied to? Shall a tunnel endpoint encapsulate IPv6 neighbor discovery packets to resolve the other node's inner IPv6 address? This is odd since there is no link-layer address to resolve since the packets are tunneled in IPv4. What is the reply?

The documentation on it is a bit thin on the ground and there don't appear to be any examples found in google but I came up with this. Forward zone:<div class="code">$GENERATE 32-41 dhcp-${0,0,x} IN AAAA 2001:db8:1234:0::${0,0,x}</div> Reverse zone:<div class="code">$GENERATE 32-41 ${0,31,n} PTR dhcp-${0,0,x}.example.com.</div> This generates addresses between 20 and 29 with the format dhcp-??.example.com and 2001:db8:1234:0::??. It's a little more complicated to do than the equivalent for IPv4 addressing as you are dealing with hexadecimal and nibbles. The 32-41 is decimal for 20-29 in hex. The 0,31,n means output 31 characters in nibble format and the 0,0,x means output in hex format. You could also change that to d for decimal. The 31 character nibble size is designed to populate a /48 sized zone file where I've just used the origin as &quot;4.3.2.1.3.8.b.d.0.1.0.0.2.ip6.arpa&quot;. Obviously addresses have been altered to protect the innocent! </description> <pubDate>Thu, 28 Jun 2012 23:54:23 +0000</pubDate> <guid>https://www.sixxs.net/forum/?msg=devel-1187384-6264546-7322994&from=rss</guid> <author>MSK13-SIXXS@whois.sixxs.net (Matt Smith)</author> </item> <item> <title>BIND IPv6 reverse generator</title> <link>https://www.sixxs.net/forum/?msg=devel-1187384-6264546-7322994-7323218-7323330-7323922&from=rss</link> <comments>https://www.sixxs.net/forum/?msg=devel-1187384-6264546-7322994-7323218-7323330-7323922&from=rss</comments> <description>Indeed, fixed too ;) </description> <pubDate>Thu, 28 Jun 2012 23:53:52 +0000</pubDate> <guid>https://www.sixxs.net/forum/?msg=devel-1187384-6264546-7322994-7323218-7323330-7323922&from=rss</guid> <author>JRM1-RIPE@whois.sixxs.net (Jeroen Massar)</author> </item> <item> <title>BIND IPv6 reverse generator</title> <link>https://www.sixxs.net/forum/?msg=devel-1187384-6264546-7322994-7323218-7323330&from=rss</link> <comments>https://www.sixxs.net/forum/?msg=devel-1187384-6264546-7322994-7323218-7323330&from=rss</comments> <description>Thanks!

Yes, the source address is valid. I've tried other packets without the 0x2b ipv6-routing header, while other fields remain the same, and those packets can be transmitted successfully. Actually, 2001:470:1f07:20c::1 is an IPv6 address provided by Hurricane Electric. If I traceroute6 from the source to the destination, it would go through:traceroute to 2001:4830:1100:1ef::2 (2001:4830:1100:1ef::2) from 2001:470:1f06:20c::2, port 33434, from port 35929, 30 hops max, 60 byte packets 1 rsquirrel-1.tunnel.tserv4.nyc4.ipv6.he.net (2001:470:1f06:20c::1) 6.636 ms 5.273 ms 5.132 ms 2 gige-g3-8.core1.nyc4.he.net (2001:470:0:5d::1) 6.335 ms 1.554 ms 8.917 ms 3 10gigabitethernet2-3.core1.ash1.he.net (2001:470:0:36::1) 9.237 ms 15.964 ms 6.995 ms 4 ibr01-ve96.asbn01.occaid.net (2001:504:0:2:0:3:71:1) 7.455 ms 7.368 ms 7.116 ms 5 bbr01-p2-1.nwrk01.occaid.net (2001:4830:ff:f150::1) 14.536 ms 14.718 ms 13.689 ms 6 bbr01-g1-0.bstn01.occaid.net (2001:4830:ff:b101::2) 20.591 ms 20.387 ms 20.192 ms 7 dcr01-g0-1.bstn01.occaid.net (2001:4830:ff:b100::2) 20.785 ms 21.948 ms 20.643 ms 8 sixxs-ic-1139-bos.customer.occaid.net (2001:4830:e1:b::2) 21.394 ms 20.598 ms 21.104 ms 9 gw-496.bos-01.us.sixxs.net (2001:4830:1100:1ef::1) 20.546 ms 21.099 ms 20.862 ms10 cl-496.bos-01.us.sixxs.net (2001:4830:1100:1ef::2) 115.745 ms 115.786 ms 105.314 ms Also, I've received no ICMPv6 packets when the packet is lost. </description> <pubDate>Wed, 27 Jun 2012 20:30:45 +0000</pubDate> <guid>https://www.sixxs.net/forum/?msg=devel-7310462-7315834-7316726&from=rss</guid> <author>YZQ1-SIXXS@whois.sixxs.net (Yan Zou)</author> </item> <item> <title>IPv6 Protocol Number 0x2b (IPv6-Route) Not Supported</title> <link>https://www.sixxs.net/forum/?msg=devel-7310462-7315834&from=rss</link> <comments>https://www.sixxs.net/forum/?msg=devel-7310462-7315834&from=rss</comments> <description><div class="quote">It turns out that all packets with protocol number 0x2b (IPv6-Route) in the Next Header field of IPv6 header are dropped inside the tunnel,</div>For SixXS I can state that we do not drop anything except what is specified in the FAQ.This should thus travel through quite fine.

When the Mobile Node switches interface from &quot;wlan0&quot; (Wi-Fi) to &quot;sixxs&quot; (AYIYA tunnel), it sends Binding Update to Home Agent and Home Agent replies Bind Acknowledgement. The acknowledgement packet has been sent to Internet (confirmed by Wireshark) but the Mobile Node could not receive that packet. I tried ping from Home Agent to Mobile Node and it worked perfectly. So I tested with the tool sendip which could generate arbitrary IPv6 packets. It turns out that all packets with protocol number 0x2b (IPv6-Route) in the Next Header field of IPv6 header are dropped inside the tunnel, while all other packets can successfully reach the other end of the tunnel. I wonder why it happens. The details of one of the dropped packets is shown below (from Wireshark): IPv6 Header:Version: 6Traffic class: 0Flowlabel: 0Payload length: 40Next header: Ipv6 routing (0x2b)Hop limit: 64Source: 2001:470:1f07:20c::1Destination: 2001:4830:1100:1ef::2 (the address of &quot;sixxs&quot; interface on Mobile Node) Routing Header:Type: Mobile IP (2)Next header: Mobile IPv6 (0x87)Length: 2 (24 bytes)Type: Mobile IP (2)Left Segments: 1Home Address: 2001:4830:1100:1ef::2 Mobile IPv6 Header:...

TSP is a combined configuration and tunneling protocol.This while for SixXS TIC is the configuration protocol and AYIYA (or heartbeat/proto-41) are the tunneling protocols. They are this similar but behave quite different. There is a huge advantage in AYIYA in that it signs every packet, as such when your local IP address changes, the next packet going out updates it. For TSP that would mean that you need to redo the full TSP negotiation, thus you will be missing several packets being sent before that transaction is complete.As these parameters do not change that is not needed. The only thing that changes is the local IP:port combination. Note that this can also be a port change on the NAT side because the NAT decided to change it, which might quite often happen in a massive NAT environment like a 3G setup. YMMV of course, and as long as things work, that is what you need. </description> <pubDate>Tue, 20 Dec 2011 17:05:05 +0000</pubDate> <guid>https://www.sixxs.net/forum/?msg=devel-1529105-4008073-6122170-6122242&from=rss</guid> <author>JRM1-RIPE@whois.sixxs.net (Jeroen Massar)</author> </item> </channel></rss> If you would like to create a banner that links to this page (i.e. this validation result), do the following:
