Limitations of desktop firewalls
If you are running a desktop firewall that blocks access to your systems ports, you might receive warnings or errors when you are starting servers, or the servers might fail to start. To work around the problem, you must give TCP/IP port access to the server process and use a SOAP connection.
Important: Applicable to WebSphere®
Application Server traditional
If there is a firewall between the development environment
and the server, use the SOAP connector port rather than the RMI (ORB
bootstrap port). The SOAP connector port is more firewall compatible.
The default setting of the SOAP port is port 8880 and selected when
you are working with a remote server. For more information, see Setting the connection to the WebSphere Application Server.To give TCP/IP port access, add a rule that allows a particular
process access to a number or range of ports.
- For WebSphere Application
Server, the Java™ process that
is used to start the server can be found at:
x:/runtimes/server_name/java/jre/bin/javaw.exe
Where x is the installation directory of WebSphere Application Server.x:/runtimes/server_name/java/jre/bin/javaw
- For the TCP/IP Monitor, the monitor is started within the development environment process.
- If you are debugging on the server, a dynamic port number is used
by default. If you want to restrict the debugger to use a particular
port, you must edit the server and specify a debug port. This is done
by using the administrative console by changing the address parameter
of the Debug Argument under the Java virtual
machine settings. For more information, see the Java virtual machine topic available in the WebSphere Application Server
information Center:
