So why not, edit /etc/crontab as follows

0 20 * * * /sbin/SuSEfirewall start file /etc/rc.config.d/firewall2.rc.config.night
0 08 * * * /sbin/SuSEfirewall start file /etc/rc.config.d/firewall2.rc.config.day

cp to firewall.configs to day|night and adapt them

snip /sbin/SuSEfirewall
------
Options:
  start generate and load the firewall filter rules from
          /etc/rc.config.d/firewall2.rc.config
  stop unload all filter rules
  close no incoming network traffic except bootp+ping (used for boot security)
  file FILENAME same as \"start\" but load alternate config file FILENAME
  test generate and load the filter rules but do not drop any packet but log
          to syslog anything which *would* be denied
  status print the output of \"iptables -L -nv\"
  debug print the iptables command to stdout instead of executing them
  help this output

Calling $0 without any option is the same as the \"start\" option.
The \"file FILENAME\" option my be used with the start, test and debug options.\n"
    exit 0
}
------
snap
