We have a situation where one Websphere server is ( should be) talking to another. Those two servers are located at different locations, and hence there are firewalls in between. The ports 9002 and 9003 are open, but the communication between the servers, seems to be happening on different ports as well. The example below is from a successful connection from client to websphere in an open LAN, wheras the connection between the 2 websphere servers fail, propably because not all ports are opened.
The ports besides 9002/9003 are somewhat random, for each connection. We don't want to open all ports, but rather limit the range of ports to open... Any idea's?
