Comment 10 for bug 1726856

I changed this:
-Before=network.target
+Before=network-pre.target
+Wants=network-pre.target

and get following:
Jul 23 09:40:53 us-proxy1 ufw-init[424]: ip6tables-restore: line 4 failed
Jul 23 09:40:53 us-proxy1 systemd[1]: ufw.service: Main process exited, code=exited, status=1/FAILURE
Jul 23 09:40:53 us-proxy1 systemd[1]: ufw.service: Failed with result 'exit-code'.
Jul 23 09:40:53 us-proxy1 systemd[1]: Failed to start Uncomplicated firewall.

When I look at /lib/ufw/ufw-init-functions:
 147 printf "*filter\n"\
    148 ":INPUT DROP [0:0]\n"\
    149 ":FORWARD DROP [0:0]\n"\
    150 ":OUTPUT DROP [0:0]\n"\
    151 "-A INPUT -i lo -j ACCEPT\n"\
    152 "-A OUTPUT -o lo -j ACCEPT\n"\
    153 "COMMIT\n" | ip6tables-restore || error="yes"

This might be realted to loopback interface not beeing configured ? So ufw starts too early ?
