In the setup I am considering, a client and a server are connected by two different networks.
The client and server eth0 interfaces are on 192.168.10.0/24 (192.168.10.1 and .2, respectively), while their eth1 interfaces are on 192.168.11.0/24 (192.168.11.1 and .2, respectively).
For some reason, I would like to access a webpage hosted in the server and send the client->server GET requests from eth0, while the responses need to go through eth1.
I tried to achieve this with NAT and iptables on the server:
sudo iptables -t nat -A OUTPUT -p tcp -d 192.168.10.1 --dport 80 -j DNAT --to-destination 192.168.11.1:80
but I keep receiving responses on 192.168.10.1.
What am I missing?

The server (x.1) is listening on port 80, but the request from the client comes from some random port. So if you want to alter the output port then you would need to know what port the client used. Your rule above will not catch the random port.
