No SNMP connection with custom template

[Colin_]

Hello everyone,

since there is no official integration for SecurePoint firewalls, I used the vendor-provided MIBs and converted them into a Zabbix template using mib2zabbix. https://github.com/zabbix-tools/mib2zabbix
I have applied the same approach to several LANCOM switches without any issues. However, with the SecurePoint template, I am encountering a different behavior:

• It appears that the Zabbix proxy is not sending any SNMP requests at all.
• There are no error messages in the frontend or logs.
• In Data collection -> Hosts, the SNMP availability icon remains grey.

The basic setup should be correct:

• SNMP is properly configured on the SecurePoint firewall.
• The corresponding firewall rule allowing SNMP is in place.
• The firewall and the Zabbix proxy are located in the same network (no routing involved).

When disabling and enabling the working and non-working templates, I receive the following log messages.

2105:20260623:102629.116 received configuration data from server at "192.168.XXX.XXX", datalen 62621 <-- Disabled working template

                                                                                                     <-- Nothing happens​

I don't know what I should check next. Any hints or troubleshooting approaches would be appreciated.
