DHCPv4 Module

Configuration Settings

The DHCPv4 module is used as a relay.

For reach request, you should set &control.Net.Dst.IP and maybe &control.Net.Dst.Port to the address of the next DHCPv4 server or relay.

Packets MUST also have a Gateway-IP-Address option, otherwise they will be dropped. This module does not (yet) support receiving replies from the DHCPv4 server. Any packets sent to the outgoing socket will be discarded.

ipaddr: The IP address we use for sending packets.

This MUST be an IPv4 address. IPv6 addresses are not supported for DHCPv4.

port: The port we use for sending packets.

The default DHCPv4 client port is 68. It should be changed from this only for testing.

interface: Interface to bind to.
max_packet_size: The maximum packet size.

Packets which are larger than this will not be sent.

Useful range: 300..1500 or so.

send_buff: How big the kernel’s send buffer should be.
