    QUESTION:

    Which ports do I need to open on firewalls for the OSD module to work?

    IPHELPER is enabled, will it be a problem?


    ANSWER:

The ports must be opened bidirectionally:

    2- Other network settings:
    - Ensure IP Helper is not used if the DHCP server is a switch. If the DHCP server is not a switch and that IP Helpser is set, ensuire that it has the name of the network boot listener 
    - Ensure that no other setting discards dhcp servers that are not specifically white-listed, as an example.
