Client Management: OS Deployment - Which ports to open on firewalls for the network boot listener to work?
Several ports need to be open between the target, the dhcp server and the network boot listener. Some configuration might have to be done specifically on the network for OSD to function.

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

IPHELPER is enabled, will it be a problem?

Can the internal DHCP Gateway from the OS Deployment (OSD) module be used if the network boot listener and the target are not in the same subnet?
1- Ports:
The following ports must be opened to be able to deploy devices. 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.


3- Enable the DHCP Gateway
This functionality requires the network boot listener to be on the same subnet than the target. It will not work even though broadcast is allowed between their subnets.
