Rational Developer for System z

Enabling firewall support

About this task

This page helps system and firewall administrators adjust the firewall rules, as appropriate when communication with Remote System Explorer or Remote Debug is hampered by firewall constraints.

In most cases, you may specify a numeric range for ports to be assigned as listening ports. Ports that connect to those listening ports are assigned by TCP/IP, generally from a pool of ephemeral or dynamic ports.

It is recommended that you avoid specifying ranges that overlap with other ranges.

You need to configure the following software:
  • Remote System Explorer. Refer to the Rational® Developer for System z® Host Configuration Guide for instructions.
  • Host Debug Tool

See Example of firewall rules on a workstation for example configurations.
