Backbox not responding to ARP

[ApertureSecurity]

good day,

So I am kind of lost in this issue. My backbox laptop can receive a DHCP lease from every router except for one. All other devices can connect to this router just fine. Upon further investigation I realised that Linux and the Router aren't speaking using ARP arp replies aren't being sent properly or something.

I found a work around though and that is to manually add the arp entries on both machines. Why is this happening and how can I fix it? It seems to be only doing this after an update on the back box machine.

arp -s  1.1.1.1  xx:xx:xx:xx:xx:xx
arp -s  1.1.1.2  xx:xx:xx:xx:xx:xx

Hi,

You can always force dhcp:

dhclient -v -r eth0 (replace eth0 with your interface)
