Zabbix Agent and Server ports?

[registration_is_lame]

For passive checks.
Zabbix server (any port) to Agent on port 10050

For Active checks
Agent port (any port) to Zabbix server 10051

Is that correct?

update: Looks like its correct.

Zabbix server to passive agent = responds to agent on 10050
Active agent to zabbix server = Active agents requests zabbix on port 10051.
