I have dedicated Dell Workstation with EVE-NG over Ubuntu.
I installed Docker(to learn it) today but noticed, it would break the networking of all routers/VM’s inside my LAB.
EVE-NG is somewhat like GNS-3 to emulate networking devices and build labs.
Router#ping 184.108.40.206 repeat 10000
Type escape sequence to abort.
Sending 10000, 100-byte ICMP Echos to 220.127.116.11, timeout is 2 seconds:
I was able to diagnose it as the ping’s on router works for 3-5 minutes after server reboot.
However, I noticed ping stops when ‘docker’ interfaces start showing up in ífconfig’.
Strangely VM Router and gateway(router) are in same subnet as well.
I have checked in my network, I’m not using 172.17.x.x anywhere.
I kept checking ífconfig’ to confirm my doubt and I was right., it’s something to do with docker. Probably when docker process started after reboot it changes something with networking of EVE-NG VM’s
I’m no expert on Linux so I think, I need to tweak few settings in networking or somewhere to fix it?
