We have severe problems connecting the NVWC through a firewall with the NV server. We have opened ports 80, 8080 and 8892, 8893 on the firewall and forced NV to use port 8893 as secondary port (with the option "-DportToUse=8893" in the "maptreeserver.reg" file ). Only one map is open. However a trace on the NVWC-Computer and the firewall shows that the NetView Server opens another arbitrary port to communicate with the Web Client. We have open a PMR. Here the answer: The process invoked is as follows:- 1. client connects to advertised server port (8893) 2. server breaks out of accept() & creates new thread w/ returnedport number to service requests for client (The Mainline Thread/Client Thread connection is still on 8893) 3. client creates thread/port to service async events, sits in accept() & informs server's new client thread of this new port number (Client creates a port for the NV Event Thread/OVw Thread connection and listens on it. It sends this port number to the server via the Mainline Thread/Client Thread connection.) 4. server connects to this clients async port (The server then connects to this port, and thus establishes the NV Event Thread/OVw Thread connection.) 5. client break out of accept() and starts listening for new async events (NV Event Thread/OVw Thread connection is established and functional.) So although the web client connects on port 8893, it will eventually drop port 8893 and listen on a randomly created port x Currently port x can't be restircted in netview, and netview is working as designed. If possible, the customer should configure their firewall to allow these connections to be made for the web client to work. Otherwise they can raise an enhancement request through their csam. I thing, this isn't a solution for our customer. Now the question: Who knows a way to get the NVWC through the firewall or to force NetView to use a certain port ? Thanks for any help Uwe
