Zabbix Over IpSec VPN

[Whitestarb5]

I am having difficullty getting Zabbix to detect agents over an IPSec VPN.

The agent is installed on the remote machine but I am not quite sure how to set up the config file.

The Zabbix server does not have a public IP and I want to route the traffic over the VPN anyway.

So in the zabbix_agentd.conf I have
Server=192.168.1.33 (This would be meaningless to the remote machine)
SourceIP=IPSec VPN Gateway IP

With detailed logging on I can see the following but no other errors.

efresh_active_checks('192.168.1.33',10051)
392:20120125:173548.350 Get active checks error: bind() failed: [0x00002741] The requested address is not valid in its context.

Is this the correct approach or should I be doing something else.

Many thanks,

Richard

For anyone who reads this my issue was with the VPN not the agent config file.
