I am working on an Arch Linux machine with an ethernet interface eth1
. I have created the interface eth1:0
using ifconfig
and given it a dummy hardware address (00:01:02:03:04:05
). When I send a UDP packet to a server application running on a remote server machine, I get back the right response. But then I see an ICMP Destination Unreachable going out from the eth1:0
interface ip address. How can I mute this ICMP message? I have tried different mac addresses and set up an arp cache on both client and server machines without success.
Appreciate any help and thanks in advance.
