Hmmm, this reminds me of a Dukes of Hazard quote: Why do something simple, if you can do it the hard way..... Why not add 192.168.1.5 as secondary IP to your machine? Otherwise, you are probably acking a static published ARP for 192.168.1.5 -Sietse -----Original Message----- From: netfilter-bounces@xxxxxxxxxxxxxxxxxxx [mailto:netfilter-bounces@xxxxxxxxxxxxxxxxxxx] On Behalf Of Julian Hagenauer Sent: Monday, June 05, 2006 1:28 PM To: netfilter@xxxxxxxxxxxxxxxxxxx Subject: Redirecting traffic from a non-existent IP Hi, i am running Linux 2.6.11.12-xen0 (binary distribution). I want to route all Traffic destined to 192.168.1.5 to 192.168.1.3. 192.168.1.5 is a non-existent IP/host, 192.168.1.3 is a Xen-VM running on localhost, so 192.168.1.5 should act as a kind of alias for 192.168.1.3 and be accessible from localhost. The following modules are loaded: Module Size Used by iptable_filter 2432 0 iptable_nat 19932 1 ip_conntrack 38712 1 iptable_nat ip_tables 20352 2 iptable_filter,iptable_nat intel_agp 20124 1 agpgart 28968 1 intel_agp I wrote and ran the following script on localhost: #!/bin/bash echo 1 > /proc/sys/net/ipv4/ip_forward MAP_FROM=192.168.1.5 # virtuelle IP MAP_TO=192.168.1.3 # IP einer VM iptables -t nat -F echo "Mappe $MAP_FROM nach $MAP_TO..." iptables -t nat -A PREROUTING -d $MAP_FROM -j DNAT --to $MAP_TO echo "Aktuelle Nat-Regeln:" iptables -t nat -L But ping 192.168.1.5 or ssh 192.168.1.5 still does not work. I have no clue what's wrong. Sincerely, Julian
