Redirect does not seem to happen on my IPv6 only server.

[scolastico]

I'v installed redsocks with shadowsocks (which is connected to a dual stack server) on my server, shadowsocks works as expected, and redsocks does start and connect to it, but if i make a call it still fails. My plan was to use redsocks to enable my server to make calls to the outside world with ipv4 if ipv6 isnt available.

I got it to work. It seems like if the server has no available IPv4, iptables will not even be called to handle the traffic. So my solution is to install bridge-utils and add this to my /etc/network/interfaces to trick the server into thinking it has IPv4 connectivity:

# [...] the other stuff from the file, just add this at the end

auto vmbr0
iface vmbr0 inet static
    address 192.168.178.1/24   
    gateway 192.168.178.1
    bridge_ports none
    bridge_stp off
    bridge_fd 0
