This can be useful if the DHCP server runs on the same server. On Linux, the response is then sent via `lo`, so packets won't be received if both sockets are bound to e.g. a bridge interface.

charon.plugins.dhcp.force_server_address = no
|
|
Always use the configured server address.
|
|
|
|
Always use the configured server address. This might be helpful if the DHCP
|
|
server runs on the same host as strongSwan, and the DHCP daemon does not
|
|
listen on the loopback interface. In that case the server cannot be reached
|
|
via unicast (or even 255.255.255.255) as that would be routed via loopback.
|
|
Setting this option to yes and configuring the local broadcast address (e.g.
|
|
192.168.0.255) as server address might work.
|
|
|
|
charon.plugins.dhcp.identity_lease = no
|
|
Derive user-defined MAC address from hash of IKE identity and send client
|
|
identity DHCP option.
|
|
|
|
charon.plugins.dhcp.server = 255.255.255.255
|
|
DHCP server unicast or broadcast IP address.
|
|
|
|
charon.plugins.dhcp.use_server_port = no
|
|
Use the DHCP server port (67) as source port when a unicast server address
|
|
is configured.
|
|
|
|
Use the DHCP server port (67) as source port, instead of the DHCP client
|
|
port (68), when a unicast server address is configured and the plugin acts
|
|
as relay agent. When replying in this mode the DHCP server will always send
|
|
packets to the DHCP server port and if no process binds that port an ICMP
|
|
port unreachables will be sent back, which might be problematic for some
|
|
DHCP servers. To avoid that, enabling this option will cause the plugin to
|
|
bind the DHCP server port to send its requests when acting as relay agent.
|
|
This is not necessary if a DHCP server is already running on the same host
|
|
and might even cause conflicts (and since the server port is already bound,
|
|
ICMPs should not be an issue).
|
|
|
|
charon.plugins.dhcp.interface
|
|
Interface name the plugin uses for address allocation.
|
|
|
|
Interface name the plugin uses for address allocation. The default is to
|
|
bind to any (0.0.0.0) and let the system decide which way to route the
|
|
packets to the DHCP server.
|
|
|
|
charon.plugins.dhcp.interface_receive = charon.plugins.dhcp.interface
|
|
Interface name the plugin uses to bind its receive socket.
|
|
|
|
Interface name the plugin uses to bind its receive socket. The default is
|
|
to use the same interface as the send socket. Set it to the empty string
|
|
to avoid binding the receive socket to any interface while the send socket
|
|
is bound to one. If the server runs on the same host and the send socket is
|
|
bound to an interface, it might be necessary to set this to `lo` or the
|
|
empty string.
