Hello, Boutin Maël a écrit :
We would like to have the Source IPv6 address of the new interface
Which address ? You know that it is common for an interface to have multiple global IPv6 addresses, or no global IPv6 address (only a link local address).
and not the IPv6 adress of the default route. Is it possible on PREROUTING hook to change the IPv6 address of the outgoing packets ?
I'm afraid not. This is not even possible in IPv4. It is possible to NAT the IPv4 source address in the POSTROUTING chain, but there is no such support for IPv6 NAT (and don't think there will ever be any).
