Hello,
Thanks for the replies!
However, this is how my dhclient.conf looks like:
interface "xl0" {
send host-name "delta";
send dhcp-lease-time 600;
}
but it does not seem to communicate with the dhcp-service from the router as the active DHCP-table
still shows the same (see below).
Any further ideas?
Regards!
