Hi Tom Isa does understand this as what I have seen But it's the how to what's been troubling me. For real if you do not know just let me know, I think this is in deed a good topic. I hope you agree, Greetz, Mario ________________________________ From: isalist-bounce@xxxxxxxxxxxxx [mailto:isalist-bounce@xxxxxxxxxxxxx] On Behalf Of Thomas W Shinder Sent: Wednesday, May 03, 2006 5:27 PM To: isalist@xxxxxxxxxxxxx Subject: [isalist] Re: VPN in ISA Server 2004 Hi Mario, I've never seen a method to do this.
