This message is displayed when Class A IP addresses are configured for LAN as Cyberoam doesnot support Class A IP addresses. Follow the below given steps to resolve the problem:
- Logon to Web Admin Console
- Go to Firewall > Local ACL
- From Auth. Network: Delete the Class A IP addresses
- Add Class B IP addresses e.g. 10.1.0.0/255.255.0.0
- Logon to CLI using SSH or Telnet and restart management services from Main menu
From version 9.5.4 onwards, it is not required to restart management services after re-configuring IP address.
