From the firewall, you can only forward a port to one ip in your LAN.
Setup your access rule to allow port 80 traffic trought your LAN.
As far as 443, remember that only one SSL can be use per IP.
Give us more details about the role of each server in your network

Hello calitech,

why do you need port 80 open to two servers?
can't you host your website(s) on one server?
just forward port 443 on the router to the internal SBS ip.
and btw, don't host website(s) on your sbs, best practice ...

you dont need to host both websites on one server!

you could have one presentation server. which catches all web requests, determins what webserver they are foor by inspecting the packet. and forwards them on to the correct host (as this server is also inside the network it is in affect acting as a proxy server)

If you have a multi nat capable router, you could purchase extra IP addresses. you could then say

if traffic comes in to ip A on port 80 forward to server A on ip address X
if traffic comes in to ip B on port 80 forward to server B on ip address Y
clients will all use IP address C to communicate in and out of the network.

in this case you may have 500 devices inside the network. all communicating externaly over 3 ip addresses. you still ahve securiy as people can externaly only see your 3 external ip address, so have no way of determining the interanal ip of your servers.

ok since I tried to forward ports 80 and 443 to my other server, I am not getting connected to my exchange server.
I turned off the forwarding of my extra server and will wait till I can get this solved.
My extra server is a Ashay backup server. They say I need ports 80 and 443 forwarded to the server.
I can connect via just not through my Outlook outside of the office.

I know I need 443 for my SBS server but I don't know if I need port 80. Should i just disable it and see what happens?

the backup server is actually Ahsay.

If I get the 2 static IPs how do I configure my router to route both IPs to the internal LAN?
Or how to I route the traffic for both ports to 2 different servers with 1 IP.

you need to insure your router has multi nat enababled.

you will also most likley need to get a block of ips (lots of ISP will allow you 8) of these you can actuly only use 6.

but if your router does not support Multi nat, then you will not be able to implement this.

the alternitive is as i said use a internaly proxy server to route the data once it is inside your network.

Looks like I might have to give up my Linksys and go with SonicWall

I am able to setup a one-to-one nat inside sonicwall. My sonicwall is setup with my old static ip of
my new block is 89-94 with a GW of 87
I setup my backup server to and setup a 1to1 nat to
how ever I can't get to my webserver from in the network or outside.
i can get to my webserver from the backup server just not any clients.

Well the One to One Nat inside the sonicwall worked. I don't know who to award the points to or just close/delete the question.
