Connecting 4 servers

Whats is the best and safest way to connect 4 servers to use one DNS server (internet Service).

I have a mail server, DB Server, another Transcation server where ISA and DNS server runs.

I want all these to be on one network usint the same internet pipe

Thanks

Internet -> Router -> 4 Computers

Thanks alot for that...

Do I have to make any special configurations to the DNS server or all other servers ...to share the DNS for the Internet service

you need to make sure that you either enable DHCP or specify the correct DNS servers on each computer.

I think what you are asking is what is the best way to share an internet connection between four servers? your wording is confusing to say the least. the safest way at a reasonable cost is as follows...

Internet<-(public ip)router(public IP)<-(public IP)PIX firewall running PAT(private IP)<-switch<-(private IP)4 servers

you will need multiple static public IP addresses and NAT 1 public IP to your mail servers private IP address and only open smtp on port 25 in your firewall for this address. deny all traffic at the firewall except what you know needs access (DNS, HTTP, etc).

do NOT enable DHCP on your servers!

all of your internal PCs should point for DNS to your internal DNS server.

By the way you worded your question however, I suggest talking to a consultant.
