Transparent proxy with IPv6 on Linux [REDIRECT target is gone]
Hi, on Linux with netfilter: previously I could do "iptables -j REDIRECT" to create a IPv4 transparent proxy. However, this is unsupported on IPv6.
How can I achieve this? iptables6 removed the REDIRECT target because it does not support Network Address Translation in IPv6.
I need the transparent proxy to work with IPv6 under Linux. How are people doing this?

Hi,
you need at least, a 2.6.37 kernel with the tproxy module:CONFIG_NETFILTER_TPROXY=m CONFIG_NETFILTER_XT_TARGET_TPROXY=m
and the last iptables release:
root@test-jp-2:~# ip6tables -t mangle -nvL
Chain PREROUTING (policy ACCEPT 5584 packets, 416K bytes)
pkts bytes target prot opt in out source
destination
60 4400 DIVERT tcp * * ::/0
::/0 socket
0 0 TPROXY tcp * * ::/0
::/0 tcp dpt:80 TPROXY redirect :::50080 mark 0x1/0x1Regards.

(Nothing was removed, it was never there.)
