I have to run strongswan and dnsmasq (providing the address pool and DNS
to the peers) on the same hardware. Apparently there is a conflict with
the local dnsmasq now. I just wonder why it didn't show for 5.6.2 ?
Shouldn't the dhcp plugin bind to a random socket to access 67/udp provided
by dnsmasq?
