Re: [FW-1] Exchange Server via VPN



Seems to me the FW is ok, it might be an exchange issue...

See if you have relaying blocked, and if so, is the FW natting you to
an IP that isnt allowed to route?

Turn on logging and see if the server is logging the transaction.
Snoop the interface with Netmon or another sniffer and see if the
session is returning packets.
