how to access / read firewall log?

I have a router (independent of my ISP) set up to forward certain communications from the external zone to a specified computer on my LAN. This particular computer is also allowed access in the internal zone to certain other computers on my LAN.

I’ve configured the firewall log for the internal zone for this computer to log all accepted and non accepted packets.

I would like to know how to access the firewall log. The log used to be in /var/log/firewall but this is no longer valid. Where is the openSUSE 13.2’s firewall log located and how can I read it?

Thanks in advance for your help. If you require further information to help me I will be glad to respond.

It logs to the systemd journal

sudo journalctl -u SuSEfirewall2

Thank you!
