[qubes-users] Firewall issue

mailinglist_bot · September 22, 2020, 5:05am

When I go into any qube settings for the firewall there is only an option to create and edit rules for outgoing traffic, nothing at all for incoming connections. Is that right? When I look at screenshots online it shows options for creating both outgoing and incoming connection rules. Latest version of Qubes.

The Qubes firewall does not support changes to incoming connections. For
that you need to start manually adjusting nftables.
By default, no new inbound connections are allowed, only connected
traffic.

For opening inbound ports, I'm successfully using this qvm-portfwd-iptables script:
