It won't help with the packet duplication, but I think it is related. I
think you will need to SNAT the traffic as it leaves 1.10 so that 1.2 /
1.20 will reply back to 1.10 rather than directly back to the client. I
think that 1.2 / 1.20 is replying directly back to the client and the
client is going WTF??? Why is 1.2 / 1.20 replying to me? I have not
started a connection with them.
As far as packet duplication, I'd start with ulogd or something like
that. I'm betting you are going to have to pass the packets to user
space for the duplication.
