Virtual networkinterface and routing

[MartinAB]

Hello,

I have two webservers (I call them web1 and web2).
Web1 is the one connected to the internet an web2 is located in my internal network. On both I use Apache 1.3.28.
Web1 works as proxy and builds the connection to web2 for clients in the internet.
Now I have configured two networkinterfaces, one physical and one virtual (eth0 and eth0:1) on web1. On the ip-address from eth0 I can access the website located on web1.
When I open a connection to the ip-address from eth0:1 the proxy-rule should redirect the clientsrequest to web2. It already works at the moment but if you watch the networktraffic on web2 all request are comming from the ip-address from the interface eth0!
I have the need that the traffic comes from eth0:1.

Could anyone give me some advice how I could handle that? It would be a great help for me!

Thanks in advance

Is that an apache proxy rule or an iptables/ipchains proxy rule. If it it the first, then that's what is supposed to be happening, if it is the second then you are clearly insane and I must stop talking to you.

Hi.

No I am using the apache proxymodule.

I need this constelation because the projects hosted on these servers are using SSL and so I need a seperate ip-address cause of the differently domainnames.

You can plumb multiple IP addresses on the same interface and assign different names to them.
