That's what I thought too, but I'm also running nginx on the same machine. I set up nginx to listen to eth0:0, and all traffic to the remote backend sees the IP address of eth0:0. However, when I try to do the same with Varnish, the backends sees the IP address
of eth0.<br>

particular route. For most traffic, the 'default' route is the route<br>

exit a particular interface--though I'm not sure if an ethernet alias<br>
will work. Try it out.<br>

<blockquote type="cite">I'm running Varnish 2.1.5 on Red Hat Enterprise Linux Server release 6.1. Currently I have two interfaces: eth0 and an alias eth0:0. I need Varnish to bind to eth0:0, which it does perfectly, however, outgoing traffic is going through
eth0. Is there anyway to tell Varnish to send outgoing traffic through the same IP address I tell varnish to "listen" to? I guess I can route the traffic accordingly via iptables, but I'd prefer to do it at the application layer if possible.<br>
