Hi, I have changed our old router over to a Vigor 2710 and configured port forwarding and open ports for ports 443 and 80 but cannot use Outlook Web Access on SBS 2003. When entering the details in a web browser it just says cannot display page, if I plug the old router back in it works fine. I have checked the list of ports on both routers and they match, is there something additional required on the Vigor.

Any help appreciated.

You need to change the router's management ports, for HTTP and HTTPS specifically - you can do that from the system maintenance - management page. Change them to 8080 and 444 for instance (respectively).
One thing you need to be aware of though is that it changes how you access those interfaces from the LAN too, so if the router's on 192.168.1.1 it would then be accessible on http://192.168.1.1:8080

Thanks Voodle, I have just made the changes you mentioned and all is working fine.
Thanks again for your reply.
