The new ipfw fwd functionality looks really nice. But it seems like Tom needs forwarding based on the name (www.domain1.com or www.domain2.com) in the HTTP GET Request. I don't think that can be handled in ipfw or ipf. One thing you could do is using both servers for both domains and use the load balancing described by Julian. This has the drawback that the servers are not separated but on the other hand you get redundancy for both servers. -- Benedikt To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-net" in the body of the message
