I'm probably looking for the 'transparant' option. > Looking at the docs it seems to do what I want... Yes, the transparent option sets IPV6_TRANSPARENT on IPv6 sockets, which should achieve this. Please let us know if this works for you; we do IP_FREEBIND only on IPv4, not on IPv6. Also, be advised that this is not supported on ancient kernels, support for those things appeared in 2.6.37. You may want to use a 3.x kernel for this. Regards, Lukas
