Re: running more than one server with one IP address
Well, you must then forward the BIND ports (port 53) also to host B.

The only way I know of doing this is if you have one externally visible IP and you're trying to break up services among systems on the internal network. On your router, you'd use port forwarding to redirect individual ports to each machine inside your network; i.e., tell the router to forward port 25 to your SMTP server, port 80 to your internal web server, and port 22 to your internal SSH server whenever requests to those port hit IP WWW.XXX.YYY.ZZZ. I would suppose you'd google for information about NAT and port forwarding on routers.

You might be better off messing with your internal DNS so people can just go to www.mynetwork.com or smtp.mynetwork.com and have your DNS server hand out the proper IP of your server(s). ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

I don't think you will be able to run different web sites from different machines if you only have one IP address (at least not easily). You can run different services on different machines though. > Wondering if someone could even direct me to the terminology that I am > looking for so I can google it. The terms you are looking for are port forwarding and Network Address Translation.

Re: running more than one server with one IP address
And about the terminology and technologies: look for port-forwarding, NAT (short for Network Address Translation), natd. Also read about seting FreeBSD as a gateway.

Re: running more than one server with one IP address
Actually for forwarding incoming ports, the NAT part is unneccessary although I have used natd for creating the port forwarding itself.

Re: running more than one server with one IP address
You create a single gateway for all the services and then use the portforwarding. This way you can forward port 25 to host A, 80 to host B and so on. The hosts A and B have to be behind this gateway machine. Much the same way LAN gateways are done. If you have some more detailed questions, just drop a line.
