License Node Limited Exceeded

Symptoms:

• Error: "too many internal hosts"
• Traffic is processed very slowly
• Operating system hangs
• The log is full of errors

There are many possible causes for this error:

• The number of nodes behind the firewall is greater than allowed by limited hosts license
• The external.if file doesn't contain the exact name of the firewall external interface
• Internal objects with Static NAT are misconfigured
• Routing tables are not properly configured
• Automatic Private IP Addressing (APIPA) on Windows is configured

Solution:

1) From the command line, stop firewall services with "cpstop". 
2) Remove the files $FWDIR/database/fwd.h and $CPDIR/database/fwd.hosts. 
3) Type "cpstart" to start firewall services. 
4) Type the command "fw tab -t host_table -x" to clear entries in the host_table table.
