Description Kapil Dakhane 2010-05-07 23:35:23 UTC
Description of problem:
The IPv6 transparency has already been implemented and Bytemobile has verified that it works correctly. It is available at:
This was verified by running ip6tables command to set mangle rules:
ip6tables --table mangle --append PREROUTING --in-interface eth2.39 --protocol tcp --destination ::0/0 --destination-port 0:65535 --jump TPROXY --tproxy-mark 0x1/0xFFFFFFFF --on-ip fdfd:6b2a:f17e::c0a8:2701 --on-port 4101
This gives following output:
ip6tables v1.4.6: unknown option `--tproxy-mark'
Try `ip6tables -h' or 'ip6tables --help' for more information.
FYI, We require this feature to claim that our product is IPv6 compliant. 

Version-Release number of selected component (if applicable):

How reproducible:
Happens everytime.

Steps to Reproduce:
1. Setup an ipv6 address for an interface
2. Issue above mentioned command
Actual results:

ip6tables v1.4.6: unknown option `--tproxy-mark'
Try `ip6tables -h' or 'ip6tables --help' for more information.

Expected results:
Command is accepted and IPv6 transparency works.

Additional info:
According to a reply on support Service Request # 2018648 :

I was able to see RFE filed to add tproxy to rhel 6 but currently the rhel 6 beta does not seem to have support for (v6) tproxy and the option --tproxy-mark . Since rhel 6 beta is not a supported release would it be possible for you to file a bugzilla regarding this case.

Comment 3 Thomas Woerner 2010-05-10 08:59:08 UTC
Is this a bug for kernel or iptables? The git repo above is kernel related.

Comment 4 Kapil Dakhane 2010-05-10 20:18:38 UTC
Both, the kernel provides the support, and ip6tables provides the utility to use it.

Comment 5 Thomas Woerner 2010-05-11 07:24:41 UTC
According to the netfilter-devel mailing list, there is still work to do on the netfilter kernel modules. The code is not accepted upstream.

Please open an extra bugzilla entry for kernel and make this one depend on the kernel bug.

Thanks, Thomas

Comment 6 Kapil Dakhane 2010-05-11 22:36:14 UTC
I filed bug 591335 for the kernel.

Comment 8 Subhendu Ghosh 2010-07-28 20:09:05 UTC
Kernel BZ moved to RHEL 6.1 pending upstream inclusion
