The original request stated that all hostnames resolve to the same IP address. In that configuration, ipchains nor iptables can be used to redirect traffic internally. When the TCP connections are made, the kernel doesn't know what hostname the client looked up to reach that address. That information won't be available until the connection is established, and the client sends the HTTP request.

Or do I have to add an loadbalancer or use an >proxy. I also thought about using ipv6, but it has an lack of supporting program's. _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
