If I have a network namespace with two network adapters eth0 192.168.11.10/24, gw 192.168.10.1 eth1 10.10.10.10/24 I can do successful pings to 192.168.10.x, 10.10.10.x and 192.168.10.1 But I cannot successfully ping 8.8.8.8. I can however successfully ping 8.8.8.8 with ping -I eth0 8.8.8.8 Is there a way to redirect processes that 'bind' to the incorrect nic, to the correct nic? I have been trying a bit with custom routing tables/rules, but I do not seem to get this to work.
