Accessing VM from outside network

[Ahmed Sabbir]

I have an Ubuntu Instance (10.20.20.122) in Microstack. I can reach outside world (i.e. google.com) from the instance, but it is not reachable from the 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 lot in advance.

As the 10.20.20.0/24 subnet is local to the host on which it is installed, you would need to add a route from the other 193.166.x.y1,y2 servers to 10.20.20.0/24 via the 193.166.x.y server.

There is a discussion about the 10.20.20.0/24 subnet here https://bugs.launchpad.net/microstack/+bug/1881054 but at the moment it looks inconclusive.

Hi Ahmed,

Thanks for reporting this. We have several bugs related to this same issue and I'm going to consolidate them. Please take a look at the bug that I'm making this a dup of. There is a new spec linked in that bug that should solve the issues reported in this bug. If it doesn't solve them, please let us know.

Thanks,
Corey
