SBS2008 with single NIC : how to use static public IP for RWW & Exchange

Hi

I'm moving from a 2 NIC SBS2003 server to a single-NIC SBS2008 Premium server. The 2nd NIC (WAN) has a public IP assigned which is different from router public IP. How can I configure the 2nd IP on the sbs 2008 server?

SBS2003:
NIC1: LAN: 192.168.0.2 / 255.255.255.0
NIC2: WAN: 139.111.112.2 / 255.255.255.248
ROUTER: 139.111.112.1 / 255.255.255.248
router model : Draytek Vigor 2820

SBS2008: as set at present
NIC1: LAN: 192.168.0.2 / 255.255.255.0

(a) do I add 139.111.112.2 / 255.255.255.248 settings to the sbs2008 NIC1 (tcp/ip>advanced)

or (b) setup some kind of forwarding on the router?

Thanks

You would setup forwarding on the router based on the IP address used.

You should also be able to assign an internal IP address to the LAN side if the vigor so that it is used as the gateway for all your devices.

Do you need to second IP address?

If not just use the one te vigor has update your MX/A records and then port forward from that IP to the internal address of your router.

SBS 2008 only supports a single nic and will not support the assignment of  a public IP to that LAN nic.   SBS 2008 requires a hardware firewall/router between the internet and the LAN NIC.
Serveral hardware router/firewall devices support multiple public IPs to the SBS NIC.
Both RWW and OWA use Port 443, so only a single public IP is required.  Then you simply connect to the specific service you want based on URL.  https://remote.domainname.com/RWW or https://remote.domaine.com/owa for email
The self signed SSL as well as most of the inexpensive 3rd party certs only support a single URL.  for wild card URL support, you're talking a lot more money for that.

You can get a SAN/UCC cert from GoDaddy that supports 5 URL's for $60 per year.

actually it's up to 72.00 per year IF you purchase a 3 year cert. (well over 200.00 plus tax)   single year is 90.00 plus tax

Thanks for the prompt response.

Draytek Vigor (192.168.0.250) includes a feature -WAN IP ALIAS- allowing the setup of multiple public ip addresses and pointing to internal IP.
