Has anyone been using a Cisco VPN Concentrator with the Software Client to
VPN into the internal network? I believe some ISPs are still blocking TCP
port 135.
Should an IPSec tunnel help with Exchange access when these ports are
blocked?

We tried ISA and VPN client with no success. We ended up purchasing a Cisco
560e PIX with VPN and it is working fantastic. I feel a hardware solution is
much better than a software one.

I'm not real familiar w/ the ISA server but I'm assuming it allows some type
of VPN connectivity. I believe I remember reading something recently about
ISA having some "secure" publishing feature for outlook. That would be a
question for the ISA folks.

No, we haven´t.

The only way for outlook to log in from the outside (even though you already
have the ip open) is to have several ports open at that address. However
opening those ports blindly to the internet == BAD. Repeat after me? ?I
will not open up my network to hackers?
Since you?re using Exch2K, You would have really two options: 1) VPN and 2)
OWA. Of course I guess you could do dial-up RAS but does anybody actually
still use that stuff? :-)
We use a combination of VPN & OWA here at our facility and have a number of
users who travel frequently with laptops. Do you have any type of firewall
in place besides the ISA server?

Hi Varga,
What services do you want to access from the external Outlook client? What
version of Outlook are you using?
Thanks!
Tom
