1. When DHCP Server enabled as Dynamic/Static IP Assignment and only
Dynamic(DHCP Server) pools are enabled,
DHCP Server not responding with BOOTP Reply on receiving BOOTP request
message.
When Static IP/IP port binding pools are enabled with respective pools, DHCP
Server responded to received BOOTP request.
This issue occurs only with Dynamic IP Assignment.
So I add
allow bootp;
range dynamic-bootp 192.168.127.70 192.168.127.99;
to dhcpd.conf,it can response the bootp client ,but the bootp not use this
response ip.
I attach the wireshark file is use tool tftpd32 dhcp server to response the
bootp client and client use normal,
And linux dhcp server packet file.
dhcpd.conf:
authoritative;
allow bootp;
subnet 192.168.127.0 netmask 255.255.255.0 {
}
subnet 192.168.127.0 netmask 255.255.255.0 {
default-lease-time 86400;
max-lease-time 446400;
range 192.168.127.22 192.168.127.55;
range dynamic-bootp 192.168.127.70 192.168.127.99;
option broadcast-address 192.168.127.255;
option routers 192.168.127.0;
option domain-name-servers 192.168.127.254;
}
