Hello, Simon Olofsson a écrit :
I would like all traffic to use the ethernet interface except traffic from a specific user. I would like the traffic from this specific user to use the ppp interface. When I try to establish a TCP connection from the specified user I see that the syn packet is sent out on the correct interface with the correct source address and the syn,ack is received, but it seems like the syn,ack is lost somewhere on my host because a new syn is sent after a while. What is missing?
Check that source validation by reversed path is disabled at least for the PPP interface (/proc/sys/net/ipv4/conf/ppp0/rp_filter=0 or /proc/sys/net/ipv4/conf/all/rp_filter=0).
