Yes, you are right, the orphan IP was a member of subnet 192.168.4.0/24 no longer used and deleted. I also removed the orphan IP.Fai le cose "Berbenne" c'è un IP orfano?
add address=192.168.4.1/24 interface=bridge1 network=192.168.4.0
I have enabled the proxy arp on bridge1 interface and now it works!! Thank you so much for your help! You have been very kind :)I would expect 192.168.3.107 is the address of your PC, did you set arp=proxy-arp on bridge1
The routes parameter was a separate issue I noticed.
ok thanks for your help anyway :)I did not study the script in detail, I only noted the common mistake of using the ethernet interface name as the indication of the internet interface where PPPoE is used.
