Hi, In book I am eating today it's writting : "if you install ISA server on a machine that already has RRAS enabled, the ISA server installation routine will disable the RRAS NAT protocol .... However we have observed unpredictable behavior on ISA servers that have the RRAS NAT protocol installed" on page 385 (me too. :-() and on this same chapter page 441 he repeat this, he want my death. I'll not told you who is he ? :-) In one of my customer, there are using RRAS and they want to use now ISA. But on RRAS filter a trainee cashes more de 7000 public address to remove de banners on web. And he configure RRAS filter outbound and inbound with this 7000 address and all users are very happy without popup and banners, I am not. Do anybody can tell how to do ? Of course I don't have an other machine, I have to stop RRAS and install ISA server in my offer. :-( I don't find info on this. -- Reagards. Gils Gayraud.
