Title: unable to get an IP address on LAN
Post by: kevin192291 on September 20, 2019, 03:36:28 am

I have a problem with the latest version of OpnSense version: 19.7.4

The Problem: The error I am getting is really odd. upon a fresh restart (power cycle OR reboot via console) I am able to be assigned an IP address from my LAN interface If I disconnect the ethernet cable, and re-connect I am never assigned an IP.

What I have checked: I believe I have the DHCP server on that interface configured correctly

my WIFI interface that is also configured and connected to an AP works just fine and always assigns an IP

LOGS: After checking the logs on the LAN interface(aka em0), I found:

Code: [Select]

Sep 19 20:53:46 dhcpd: send_packet: No buffer space available
Sep 19 20:53:46 dhcpd: DHCPOFFER on 192.168.1.100 to 00:22:20:13:89:e6 (kevin-V110) via em0
Sep 19 20:53:46 dhcpd: DHCPDISCOVER from 00:22:20:13:89:e6 (kevin-V110) via em0
Sep 19 20:53:43 dhcpd: dhcp.c:4056: Failed to send 300 byte long packet over em0 interface.
Google Searching: I found only a couple of articles, one was another question here on SE, however... I don't think it is useful in my case... https://askubuntu.com/questions/811817/failed-to-send-300-byte-long-packet-over-wlan2-interface

What I am wondering...: Is there anyone that has experienced this, or knows if I can make this work... I hate having to reboot every time I want to connect a computer to LAN

Update 1: I want to add, I have checked and verified that the built-in rule to allow UDP traffic to LAN(em0) on port 67 is there and is active.
