High ARP Incoming
Posted: Thu Apr 07, 2016 6:51 pm
can anyone tell me why this is happening. i am facing this at incoming direction.
that interface is connected to a city wide lan of my isp and have a /24
The problem could be that the provider offers proxy-arp on their router, and the customers do not bother to seti have seen /22 subnets without this behavior something has to be wrong
No, that is not difficult at all! Just trace to a file and examine it in wireshark.so ether2 is ur inbound traffic from ur ISP to ur router? but why not using ur ether1 interface?
im curious too what packet is that. based on my experience, its very difficult to trace who sending it and what add they arping it.
I hope you have a default route configured to point to their gateway and others do that as well.well my isp use a router called flash router made by http://ipacct.com/en/home/. they give me one ip address and i configured NAT on ether2.
and they run PAT on their router. before that flood my ARP configuration was just enable, after that i make the gateway in ip/arp static and interface arp reply only.
