Log file containing dhcp client requests?

I'm trying to locate the logfile that would track the firewall's own client dhcp request over a WAN connection when trying to get an ip from a Cradlepoint modem? My XG210 (SFOS 19.5.1 MR-1-Build278) is having trouble, but when I connect my laptop to the modem it gets an IP almost immediately. I have also noted that when the modem is disconnected or goes offline, the network display shows it is disconnected but also still shows an IP address assigned. I have been working with Cradlepoint and we still haven't figured out exactly why we sometimes get an ip, but most times don't on the firewall.

    seems /log/garner.log contains this information...

  • I'm not finding anything in garner.log that includes "Lease IP" or "renewed". I can't search for an IP address like you did as it is dynamic, not sure what it might be. On my system it appears I am seeing this in the networkd.log file though it is difficult to tell which port is being renewed. The IP is what I expected though.

    Success

    I need to go out to my remote site and see what is happening in the system that is failing now.
