[sf-lug] Anyone familiar with FreeBSD used as a reverse proxy?

[opeters at pacbell.net]

I've got a FreeBSD server I am using as reverse proxy, which forwards Outlook Web Access requests to the Exchange server. The motherboard failed on the server. I pulled the hard drives out of the bad server and built a new server with the old mirrored drives.  The system pings just fine. It won't, however, forward requests for the OWA.  Any thoughts on this???
 
Any and all would be appreciated!
