<p>Hello,</p>
<p>I have a problem with the DHCP plugin.<br>
I have Strongswan and DNSmasq on the same host (my Linux gateway)
and would like to issue IP adress from local LAN to remote access
users, however, I cant get it working. In the logging I can see
Strongswan sending DHCP Discover, and DNSmasq responding, however
directly after DNSmasq gives a strange error.</p>

10.1.1.1 is my gateway. 10.1.1.63 is broadcast adress (local LAN 10.1.1.0/26).
I have also tried changing broadcast in charon settings to 255.255.255.255, but then there is no DHCPOFFER seen in the logs.

Below is my DHCP-plugin config.
dhcp {
# Always use the configured server address.
force_server_address = yes
# Derive user-defined MAC address from hash of IKE identity.
# identity_lease = yes
# Interface name the plugin uses for address allocation.
interface = br0 # Local interface where DNSmasq is listening
# Whether to load the plugin. Can also be an integer to increase the
# priority of this plugin.
load = yes
# DHCP server unicast or broadcast IP address.
server = 10.1.1.63
}
