Hi all
I have a real problem. My client has an NT network and a permanent
connection to the Internet. For email they use MS Exchange over X.400. They
also have a few Unix systems around. They want to protect their machines
from the Internet and also control outbound access to the Internet.
I thought MS Proxy Server 2.0 was a good idea. It uses NT logon details to
authenticate who can access the Web (they have to belong to a group called
Web Users).
BUT... after six weeks on the phone to Microsoft, they tell me that the
Exchange X.400 MTA doesn't work through their Proxy Server as it's not
Winsock-compliant. Yikes!
X.400 is non-negotiable. I can't just switch to SMTP. I don't want to put
the mail server on the "wrong" side of the Proxy Server as it has too much
other stuff on to be exposed like that. Therefore, I need to switch to a
different firewall. Linux seems a good bet, and the TIS toolkit seems to
get me a long way, but I am concerned about integration. I would rather
allow/deny access based on user, not just IP address. Is this possible
under Linux, with the facilities available?
All suggestions gratefully received.
