Hmm, if I change the function like so:
interface_is_usable() # $1 = interface
{
[ "$1" = lo ] && return 0
interface_is_up $1 && [ "$(find_first_interface_address_if_any $1)"
!= 0.0.0.0 ] && run_isusable_exit $1 && echo "interface is usable: $1"
interface_is_up $1 && [ "$(find_first_interface_address_if_any $1)"
!= 0.0.0.0 ] && run_isusable_exit $1
}
Then run shorewall start I get:
$ shorewall start
[ -f /var/lib/shorewall/firewall ]

If I check /var/lib/shorewall/firewall I see that the "not Added" comes
from an "if" here:
if [ -n "$SW_PPP1_IS_USABLE" ]; then
...
else
error_message "WARNING: Interface ppp1 is not usable -- Provider
pppp1 (12) not Added"
fi
I can't see any other reference to "$SW_PPP1_IS_USABLE"? The if for
eth0/wlan1 both use interface_is_usable, only the ppp1 statements are
different?
This is shorewall 4.4.22.1
Thanks for any thoughts?
