The question is irrelevant as 'ping' uses a specific TCP/IP port, which Grid Control doesn't use.
So it is quite possible you are unable to ping the server, and are able to access it, because relevant ports are open and the ping port isn't.
Obviously when the relevant ports can't be accessed directly by server1, you won't be able to monitor the database server from server1 directly.
telnet server3 <port number> and telnet <server1> portnumber in some cases should be able to tell you that.
The only way out is to install an extra Oracle Management Server on Server2, and the OEM repository on Server1. In that case the relevant ports should be open between server2 and server3.
Now, as I don't know the port numbers by heart, this question ends up with you reading.... TADA... the one thing you tried to avoid: THE DOCUMENTATION.
