2 IP on server .. FIM issue

2 IP on server .. FIM issue

I have server1 EventLog Analyzer with IP: 
and have another server2 with 2 IPs:
public IP - 176.xx.xx.xx/24 default gw 176.xx.xx.xx
and private IP:

in Admin (FIM) .. I;m added server(agent): with Private IP

Server2 - send rsyslogs to server1 without any issues... but when i tring to use FIM ... got nothing

The reason that server2 (EventManagerLogAgent)
sends request to Server1(EventManagerLogAnalyzer) with public IP:

because of this... got nothing :(
it will be greate .. and I can put variables like
agent_ip in config files
