Specify the DNS or TFTP server for forwarding DNS or TFTP requests, or specify a
destination server address for forwarding LAN broadcast packets as unicast traffic for a
custom-configured UDP port.
When configuring port helpers, in releases prior to Junos OS Release 17.2, only one server
can be specified for a given port. For Junos OS Release 17.2 and later, multiple servers
can be specified for a given port at the global or interface-specific level. When multiple
servers are specified, the same packet, with the originator IP address and port requests,
is forwarded to the different configured servers; the payload of the UDP packet is not
modified.
