How to monitor a host in the internet?

[bondbig]

Hi, ALL!
Zabbix server 1.6 is installed and several hosts monitored successfully. Zabbix server is located in LAN, monitored hosts are in LAN and DMZ. But yesterday one of the hosts was moved to the internet, so zabbix server has lost contact with it, to be more precise one-way contact is still available (from zabbix --> to host), but it doesn't help. The solution could be in creating static-NAT of public ip to zabbix server (e.g. move zabbix server to DMZ), but this solution is not suitable for several reasons.
The question is - whether zabbix can monitor a host with one-way connection (port 10050)?

solved, i just needed to edit zabbix_agentd.conf on remote host and change "Server=" to the firewall external ip, so zabbix_agentd could accept connections.
zabbix_server (LAN ip)--->FireWall(NAT, public ip)--->Host (zabbix_agentd, "Server=FW public ip")
