Hello,
For several days, I have had a strange manifestation.
2 windows machines (the only ones) are completely blocked (but the internal ping work).
I thought of a network card pb but after 3 days I understood that the ARP table posed the problem.
When I say pose the problem, I am not incriminating ARP, but it turns out that when I delete the ARP entries corresponding to my 2 windows machines, the internet is functional.
The IP and mac address with two machines are OK in ARP
My DNS is with the router ip + 1.1.1.1 And the DHCP is managed by the router too.
My setup is very simple.
However, both windows machines have this reaction.
I also find that on Debian, if I ping 1.1.1.1 it's OK.
But if I ping google.com then it doesn't work.
I have a big problem, and I humbly ask for your help.
Regards
