netfilter for IPv4 and IPv6

netfilter for IPv4 and IPv6

[Jose Luis Faria]

[-- Attachment #1: Type: text/plain, Size: 648 bytes --]

Hello,

I have some servers and others machines already in IPv6, some of them 
are firewalls.

The firewalls are dual stack:IPv6 and IPv4. I must use iptables for IPv4
and ip6tables for IPv6, it means, the same firewall must filter packects 
from
IPv4 machines and IPv6 machines.
I'm looking for any help in the net but I can not find any help about this.

What can I do to solve this problem?
Any ideas?

thanks in advance.

iptables (with a correctly compiled kernel) supports both ipv4 and ipv6.

Did not think that iptables manipulates the ip6tables.

On my setup I use both iptables and ip6tables to create/maitain 2 sets
of tables.
