I have an Ubuntu Instance (10.20.20.122) in Microstack. I can reach outside world from it but it is not reachable from outside network.For example, from the host (physical) LAN it is not reachable ( it is reachable only from host). There is a br-ex (10.20.20.1) bridge already available with the installation of Microstack. My host is Ubuntu 1804 Desktop Host IP is 193.166.x.y I want to ping the instance from other hosts as well (such as 193.166.x.y1,y2,y3.. etc.). Your help/suggestion is greatly appreciated. Thanks a million.
