1. Troubleshooting
This section describes procedures for troubleshooting problems you may encounter with Portbase, and is
divided into the following sections:
z Installation Problems
z Configuration Problems
z Intermittent Problems
z Protocol-Specific Problems

different port.
ƒ Troubleshooting Network Configuration Problems

Portbase must be on the same logical network as your host computers (e.g., if your computer has
an IP address of 192.189.207.3 and the subnet mask of 255.255.255.0, Portbase should have an
IP address of 192.189.207.x, where x is an integer between 1 and 254), or you must properly
configure your router address to work with Portbase.
z If your Device Server is set to Auto or DHCP for obtaining an IP Address, it is possible that
