After installing SEP SBE cloud, or enabling the SEP SBE cloud firewall, clients are no longer able to map network drives, or detect other network resources such as printers and scanners.
Network resources are not accessible that were available before installation of SEP SMB cloud or enabling the SEP SMB cloud firewall.
The SEP SMB cloud firewall is blocking inbound connections on ports 139 and 445.
To address this issue, modify the SEP SMB cloud firewall policy to allow for inbound connections on ports 139 and 445. To do so, follow these steps:
The policy will now be distributed to all clients currently online and connected to the web portal manager. Once the policy distribution is complete, attempt to connect to the mapped drive, or access the printer.
If issues persist after creating and distributing this policy, isolation troubleshooting would be called for to verify that this is an issue with the SEP SMB cloud firewall. Please refer to TECH216423 for steps to disable the SEP SMB cloud firewall for troubleshooting purposes.
