WatchGuard SNMP with Zabbix

info.txt

Monitoring a WatchGuard with Zabbix via SNMP isn't as well documented as you'd hope, but it's also not difficult.

Step 1) Install this template into Zabbix: https://share.zabbix.com/network_devices/watchguard/firebox-watchguard-m400

Step 2) In your WatchGuard, go to System > SNMP. Select SNMP v1/v2c. Create a community string. 

Step 3) In your WatchGuard, go to Firewall > Firewall Policies. Create a new policy allowing SNMP from your Zabbix server.

Step 4) Create the host in Zabbix. Remove the Zabbix agent entry. Add an SNMP entry. Leave port 161. Assign the WatchGuard to a group.
Add the "Halley Firewall Watchguard M400" template (unless you renamed it). Go to "Macros". Add "{$SNMP_COMMUNITY}" and
make sure it's value is the SNMP community string you created. 

Step 5) Be patient. We had to wait overnight for bandwidth statistics to start populating.
