New firewall maintainer here. I'm working on the backlog bugs. Sorry for the delay. I had a look at the code and couldn't find why the "zone:" syntax shouldn't work any more. Especially since FW_MASQ_DEV="zone:ext" is the default value, if nothing else is specified. Do you still have this issue? If so can you please provide additional information: - which openSUSE distribution are you currently using - output of `zypper info SuSEfirewall2` - output of `journalctl -u SuSEfirewall2` using the broken configuration - the /etc/sysconfig/SuSEfirewall2 config file that causes the problem Otherwise please report back so I can close this ticket. Thank you
