Hello,
For a small business that host it's own exchange, website, and local network server how will having multiple IPs be beneficial? 2010 Exchange is on the 2008 R2 DC all on one physical hardware with a 2 port NIC.
Since the extra IPs are included in the ISPs base package should I just utilize them separating out the MX-record, Website ip, ftp IP, and wan traffic all to different IPs?
The router uses one main static IP but is also 1 to 1 NAT capable.
The server has a 2 port NIC but the only setup I can think is to use one port for the Local network and the other for the external WAN traffic possibly even using 2 vlans. But that really doesn't help much in the way of speed improvements using multiple external IPs. Now if it had 4 ports then maybe I could separate out internet traffic from exchange email traffic but it doesn't have 4 ports. or do I even need 4 ports, can I just send all external IPs to one port and separate out internet, ftp, and exchange traffic from there?
Does the external port need DNS or DHCP since the LAN port would be hosting that. The connections would not be bridged.
Does this sound like a good setup or can anyone else give me better recommendations for the use of these multiple IPs? I won't be adding hardware, the current server is new with very nice specs and highly capable of hosting everything on one physical server.
Thanks,
Cilantro
