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:

FireWall-1 NG: 
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.
