inet addr:80.109.145.85 Bcast:80.109.145.255 Mask:255.255.255.0
this net mask is not suitable for this ip
this ip should get the mask 255.0.0.0
Gateway: 80.109.145.255 this not a broadcast address in this case because you’re using the B class of ip.
and dont forget this is a public IP,it wont work like this
try private ip like 192.168.1.X/24 or 172.16.X.X/16
good luck
