bitmask-root: firewall not working on Debian buster
I have installed the packages bitmask and bitmask-vpn from package source
deb http://deb.leap.se/client release buster
The VPN connection is working:
bitmaskctl vpn status
...
status off
firewall off
vpn on
domain riseup.net
remote 212.83.143.67:443
84.0 B
180.0 B
... but the bitmask-root firewall is not.
Calling bitmask-root directly failed:
sudo bitmask-root firewall start 192.168.1.1
bitmask-root: ERROR: Could not run ['/sbin/iptables', '--new-chain', 'bitmask']: None
The iptables package is installed.
