Thank you for discussing the merits of dummy interfaces. I will consider your arguments. But unfortunately this did not answer my question. Let me rephrase it: Is it a good idea to set a specific global IPv4 address as source address for outgoing ICMP error messages? Would it be OK to create a /proc/sys/net/ipv4/icmp_errors_source where you could write an arbitrary IPv4 address into? And that would get used as the source address of ICMP errors? My questions did contain the loopback interface as I first thought it a good source of a globally routable IPv4 address (at least in our case). Secound thought: Instead of writing an IPv4 address to /proc/sys/net/ipv4/icmp_errors_source write an interface name to that file and take the first global IPv4 address from that interface as source for ICMP errors. Then you could create a dummy interface for that use case, too. Still: Is it a good idea to do so?
