[Ferm] Any way to SNAT in IPv6 ?

[Christophe]

Hi list,

I use ferm in many cases , and is really a marvelous tool.
But I have a singular case to handle. I need to get SNAT target with
ip6tables working while using ferm.

the ip6tables syntax is the following :
ip6tables -t nat -A POSTROUTING -o eth3 -j SNAT --to 2a01:xxx:xxx:xxx::2

I used the following syntax in ferm.conf :

domain ip6 {
    table nat {
        chain POSTROUTING {
                outerface $out_if2 {
                       SNAT to $host_gw2_snat;
                }
        }
    }


    table filter {
...
...
...
    }
}

And the result is :
root at gwv6:~# ferm --interactive --timeout /etc/ferm/ferm.conf
ip6tables-restore v1.4.14: unknown option "--to-source"

Problem seems that syntax differs from iptables, that uses
'--to-source', while ip6tables uses '--to'.

Is there anyway to get this work with ferm syntax ?

Christophe.
