If selected, udhcpd will base its selection of IP address to offer

on the client's hardware address. Otherwise udhcpd uses the next

consecutive free address.

This reduces the frequency of IP address changes for clients

IP address.

help
|
|
Some buggy DHCP servers send DHCP offer packets with option
|
|
field larger than we expect (which might also be considered a
|
|
buffer overflow attempt). These packets are normally discarded.
|
|
If circumstances beyond your control force you to support such
|
|
servers, this may help. The upper limit (924) makes dhcpc accept
|
|
even 1500 byte packets (maximum-sized ethernet packets).
|
|
|
|
This option does not make dhcp[cd] emit non-standard
|
|
sized packets.
|
|
|
|
Known buggy DHCP servers:
|
|
3Com OfficeConnect Remote 812 ADSL Router:
|
|
seems to confuse maximum allowed UDP packet size with
|
|
maximum size of entire IP packet, and sends packets which are
|
|
28 bytes too large.
|
|
Seednet (ISP) VDSL: sends packets 2 bytes too large.
