  • No prob, let us know how it goes. Also, thinking more about it, you may want to go the static IP route for 2 reasons

    1. You wont be introducing a 2nd dhcp server to your home/production network
    2. You’ll always know the IP of the guest VM(s)

    w/ regards to the first issue I guess you could just allow :53 and bootps from the dhcp subnet that virt manager created. Something like
    sudo ufw allow from 192.168.122.0/24 to any port 53 where 192.168.122.0/24 is the subnet virt-manager created for dhcp

    I think that’ll allow both tcp and udp. I haven’t used ufw in a while, my RHEL based distros switched to firewalld, but the concepts are the same, just different syntax. I do believe you’ll need udp open as IIRC during DORA the initial DISCOVER is sent over udp, and somewhere between OFFER and REQUEST it switches to tcp…but I also haven’t had to troubleshoot dhcp in a while, and I have forgotten a lot. Either way let us know how it goes!
