We are currently having exactly the same problems. Our security guys said that we have two options:1) Configure the grid so all communications are opened from the grid, no connecting from the server side.
2) Use proxy.We asked an expert to solve this for us. I will tell you when we have an answer.

Hello all,Grid Control 10.2.0.4, Agent in DMZ 10.2.0.4, Solaris 10I read through the awful, unorganized, repetitive and confusing documentation regarding configuring communication through a firewall to reach a target in the DMZ. It states that you must use a proxy server to communicate from the target back to the management service. Well, I don't have a proxy server available for that purpose. Has anyone successfully set up communication for this purpose via ssh tunnel?Thanks//Lisa Koivu// //Oracle Database Administrator// //desk: 407-903-4691// //cell: 954-683-4459//This electronic message transmission contains information from the Company that may be proprietary, confidential and/or privileged.
