Hello, I'm seeing in my firewall log unknow UDP traffic which is caused by the running dhclient: Jun 3 21:57:02 c720-r276659 dhclient[2601]: send_packet: Network is unreachable Jun 3 21:57:02 c720-r276659 ipmon[2368]: 21:57:02.751350 ue0 @0:82 b 10.42.0.83,68 -> 10.42.0.1,67 PR udp len 20 328 OUT Jun 3 21:58:38 c720-r276659 dhclient[2601]: send_packet: Network is unreachable Jun 3 21:58:38 c720-r276659 ipmon[2368]: 21:58:38.753118 ue0 @0:82 b 10.42.0.83,68 -> 10.42.0.1,67 PR udp len 20 328 OUT What is my dhclient asking from the router 10.42.0.1?
