You can see the current network of your project from the [https://juno.calculquebec.ca/project/network_topology/ Juno webpage]. There you see the three basic networks available to all projects: <code> <myproject>_network </code>, where you VM lands by default, it is the ''local area network'' (LAN) of your project; the <code>Public-Network</code> that is the internet, you see that a router named <code><myproject>_router</code> is connecting your LAN to the internet; <code> CephFS-Network </code> is the CephFS file system network; you need to connect your VM to that network to [https://docs.alliancecan.ca/wiki/CephFS access CephFS volumes]. | You can see the current network of your project from the [https://juno.calculquebec.ca/project/network_topology/ Juno webpage].

=== Networking & Security Groups === | |||
To get & retain IP connectivity via DHCP, an instance must be able to receive DHCP leases and renewals. If you are setting custom security groups, be sure to add some rules for DHCP: egress to 0.0.0.0/0 UDP port 67, and ingress from 0.0.0.0/0 UDP port 68. Leases last 12 hours, and if the instance is unable to renew it upon expiry it will lose IP connectivity. | |||
