I wonder if anyone is running IPv6 under Centos-5.2?
YES!!! On some systems it is strictly IPv6. IPv4 only on lo loopback.
Particularly with shorewall?
NO!!!
I see that shorewall6 is specifically designed for updating shorewall to IPv6, as described in http://www.shorewall.net/IPv6Support.html.
Unfortunately, this explicity requires kernel 2.6.25 or later, and iptables 1.4.0 or later, both of which are later than any versions I've seen on a Centos repository.
Tom was rather explicit about why we will NOT see Shorewall6 with Centos and the 2.6.18 kernel:
"2.6.18 doesn't support stateful IPv6 firewalling at all!"
I think that says it. You want stateful IPv6 firewalling, then you will get a newer kernel which means most likely Centos 6.0...
I'm wondering how safe it would be to install Fedora versions of the required kernel and iptables?
I seem to recall kernel discussions here on this list and why this is a VERY bad idea.
Or is there any alternative to shorewall that is IPv6 compatible? I don't really want to run iptables directly, unless forced to do so, as I have found shorewall very reliable and simple to configure.
What I am working on is a FC9 system with shorewall6, then doing a ip6tables -L and copying those rules that do not require stateful firewalling...
