Solved: dhclient spams system log with DHCPREQUEST on ... to ... port 6x

(1/1)

Hi all!
If you see at System - Log Files -General a lot of lines like
DHCPREQUEST on [WAN-Interface] to [IP other than 255.255.255.255] port 67 (or 68)
the solution could be:
Add this line at Interfaces - WAN : Option Modifiers (last line)

supersede dhcp-server-identifier 255.255.255.255

In my case the dhclient tries to fetch the cable modem's external IP from my provider with his last known private IP address - which fails. After several tries it releases a broadcast at 255.255.255.255 wich finally succeeds.
To supersede this behavior seems to be the solution...
