 * You can't enable a [liveness probe](container-instances-liveness-probe.md) or [readiness probe](container-instances-readiness-probe.md) in a container group deployed to a virtual network.
 * Due to the additional networking resources involved, deployments to a virtual network are typically slower than deploying a standard container instance.

 * For inbound connections, the firewall should also allow all ip addresses within the virtual network.
