outlook web access port forwarding

Hi all,

a quick and easy one hopefully.

I am going to install SBS2008.
I want OWA to work from external clients.

Do I NEED to have a second external IP to use as port forwarding on port 443?

thanks very much
Gareth

no, you can create an A record on your external DNS then configure your firewall to allow port 443 to your server

Yes(considering only if you can not forward 443 port from 1st public IP). You will need public IP & your firewall/routing device needs to forward 443 port to exchange server.

Consider having Exchange certificate also in your planning.

so as long as I am not using 443 originating outside for anything else I can do it on the 1st ext IP?

on the firewall something like
all connections originating outside on port 443 will be NAT/port forward to intenrla mail server.

to check, communiction on 443 originating from inside will not be affected by this.

correct
if you host multiple web sites on one server you only need one ip address
you can make the sites unique with a unique host header name

- Yes. If your 1st Live IP is not being used for Traffic from Outside on port 443 to forward/NAT to internal host you can use it.

Firewall settings will be like
Source- Any | Service 443(SSL) | Destination Exchange Server|

to check, communiction on 443 originating from inside will not be affected by this.
i did not understood correctly on your question but if you have already any service which is being used on Live IP for SSL it will be affected. If you are asking any external site/internal site browsing on SSL port using that firewall then they will not be affected.
