TCP/IP command. Internet Boot Protocol Gateway. Maintain a gateway that forwards bootpd requests to server. In addition to dealing with BOOTREPLY packets, also deal with BOOTREQUEST packets. bootpgw is normally run by /etc/inetd by including the following line in the file /etc/inetd.conf:
bootps dgram udp wait root /etc/bootpgw bootpgw
This causes bootpgw to be started only when a boot request arrives. bootpgw takes all the same options as bootpd, except -c.
