Re: How to config Activesync for LAN/WAN access with Small Bus 2

Hi,
If you want to sync with different IP addresses internally and externally,
you need to use a DNS name that is the same for both. So you would have to
setup a host name in your public DNS as well as in the SBS server so you can
access the server by the same host name in both locations.

Then switch to using the new host name instead of the IP address.
