routing eth0:1 directly to kvm VM

  • 772

Ive got a Dedicated Server with 2 Public IP Adresses and would like to route all eth0:1 traffic to a KVM Guest via iproute2 or even iptables. Outgoing Traffic should also be routed to eth0:1 - eth0 and eth0:1 are assigned in different Subnets.

Setup is/should be as following: 178.1.2.3 eth0:1 <-> 192.168.1.254 br1, gateway for tap1 <-> 192.168.1.1 KVM Guest

  1. This seems way too complex. Just bridge the VM and set the IP address in the guest.

  2. it actually was surprisingly simple:

    -A PREROUTING -d 178.1.2.3/32 -j DNAT --to-destination 192.168.1.1
-A POSTROUTING -s 192.168.1.1/32 -j SNAT --to-source 178.1.2.3

    thanks anyway!
