The current link in the wiki links to my own gitlab repo, which is normally the same template as in the Official Zabbix community templates repository (and may even be more recent at some point as I will continue development there and there will always be a delay in submitting changes to the community templates repo.)
I have also submitted a request for this IPFire template to be listed on the Zabbix Integrations platform; When/if that is accepted by the Zabbix team, I will put a link on the wiki to the Zabbix Integrations page for IPFire.
