--- Comment #53 from michael.faille@gmail.com --- Hum, finally, I have the problem when I run a container... and my default route change !
Before starting docker $ ip route default via 192.168.1.1 dev wlp3s0 proto static metric 1024 172.17.0.0/16 dev docker0 proto kernel scope link src 172.17.42.1 192.168.1.0/24 dev wlp3s0 proto kernel scope link src 192.168.1.100 192.168.122.0/24 dev virbr0 proto kernel scope link src 192.168.122.1
After starting docker $ ip route default via 192.168.0.1 dev vethyzDqJ5 proto static metric 1024 172.17.0.0/16 dev docker0 proto kernel scope link src 172.17.42.1 192.168.0.0/24 dev vethyzDqJ5 proto kernel scope link src 192.168.0.50 192.168.1.0/24 dev wlp3s0 proto kernel scope link src 192.168.1.100 192.168.122.0/24 dev virbr0 proto kernel scope link src 192.168.122.1
The problem persist with firewall activated : sudo systemctl stop firewalld # and start container
sudo sysctl -a | grep ".forwarding net.ipv4.conf.all.forwarding = 1 net.ipv4.conf.default.forwarding = 1 net.ipv4.conf.docker0.forwarding = 1 net.ipv4.conf.lo.forwarding = 1 net.ipv4.conf.p3p1.forwarding = 1 net.ipv4.conf.virbr0.forwarding = 1 net.ipv4.conf.virbr0-nic.forwarding = 1 net.ipv4.conf.wlp3s0.forwarding = 1 net.ipv6.conf.all.forwarding = 1 net.ipv6.conf.default.forwarding = 1 net.ipv6.conf.docker0.forwarding = 1 net.ipv6.conf.lo.forwarding = 1 net.ipv6.conf.p3p1.forwarding = 1 net.ipv6.conf.virbr0.forwarding = 1 net.ipv6.conf.virbr0-nic.forwarding = 1 net.ipv6.conf.wlp3s0.forwarding = 1
