This is how my test environment looks like. The 'host route' which I create with 192.192.168.114 is so health checks reach the container. This route is only set if the ip range is different from the range of the host. ip netns add testing ip link set testeth0 netns testing ip link set testeth1 netns testing ip netns exec testing bash ifconfig testeth0 192.168.10.232 ifconfig testeth1 cc.cc.cc.43 # until this, enough to ping networks # can ping 192.168.10.333, 192.168.10.2, cc.cc.cc.1 # not: own ip's?? cc.cc.cc.43, 192.168.10.232 ip route add default via cc.cc.cc.1 dev testeth1 table 81 # necessary for the host 192.192.168.114 to ping cc.cc.cc.43 ip route add 192.168.10.114 dev testeth1 scope global table 81 ip rule add from all to cc.cc.cc.43 table 81 ip rule add from cc.cc.cc.43 table 81 # can ping dd.dd.dd.130
