I have successfully created firewall rules by the two methods in QubesOS:
qvm-firewall- the python script in the host OS (dom0) which writes to
/var/lib/qubes/appvms/<vm-name>/firewall.xmland outputs my rules with:
qvm-firewall <vm-name> list
- The GUI: Qubes Settings > Firewall Rules
But I cant find information in the docs on how and where my rules are then implemented. Iv been looking in
iptables -L -v on the relevant netVM and even in the appVM and I dont see the implementation of the rules I defined anywhere. Please can someone provide more information or a link to more information on how and where my rules are implemented?
