First of all, I'm new to zabbix.
I have a MIB file provided by Fortigate (Fortinet firewall device) to monitor with SNMP.

I know I can't use the mib file as a zabbix template but I can't find a way to convert the mib to an XML template for zabbix.

I read somewhere that it is possible to use the mib file but I have to import it into the mib directory using ftp on the zabbix server, is this a solution?

I already tried 2 different projects that help convert mib to XML model but they don't work.
