I’m running Windows 2008 as a domain controller, DNS, DHCP & Exchange 2007 and a separate Windows 2008 server running Forefront TPM 2010. Two networks INTERNAL (192.168.1.x) and EXTERNAL (10.0.0.x ) all basic functionality appears to be working. Having used the very useful guides on the this site I have successfully published the Exchange OWA functionality but ActiveSync is not working. The current state of play is a follows:
In summary when connected to the INTERNAL network all is working, but ACTIVESYNC fails when used externally. All server certificate & internal/external DNS correctly resolve to mail.domain.co.uk
I’ve assumed the ActiveSync connects using the OWA configuration, or is there a need to setup a separate rule to publish the ActiveSync HTTPS connection? Ideally I would like to use https://mail.doaminname/ using some of the OWA redirection but before fiddling with this I would like to get the basics working correctly.
One final question, once I have this all working I wouldn’t mind adding Forefront Exchange to the Exchange 2007 server, are there any howto guides that may help?

FWIW, I got this working just the other day on my new TMG 2010 array installation by creating just one rule on the Firewall Policy page. I'm not sure what had to be done on the Exchange side, however, as I don't manage that server.
