Hardware: UTM 120
Software: 9.105-9
Today i had a call from a customer, that the Internet isn't working.
When i've got to him, the System Logfiles says many lines with "2014:02:06-08:05:40 fw01-1 dhclient: DHCPREQUEST on eth1 to 255.255.255.255 port 67" but the UTM didn't get an IP from the Modem from the ISP.
I restartet the Modem and disabled the WAN Port for 10 Seconds and then enabled it again. The UTM now sends an DHCPDISCOVER and the IP is beeing updated. Does someone now why this is happening? I thought that the UTM should send an DHCPDISCOVER when the DHCP Server could not be contactet and not only when the Interfaces was down for a second..
