asked on

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

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.
