Kvm isolated network

[Claudio Carboncini]

I tried to virtualize the Debian-edu network with virt-manager + Kvm
following https://wiki.debian.org/DebianEdu/HowTo/TestCDinstall with
debian-edu-11.3.0-amd64-BD-1.iso.
The installation works, but I can't connect from 10.0.2.2 with the outside.
The network is isolated.
Any suggestions to fixing the problem?
Thanks
Claudio
