I want to have one ISP on 1 external interface and another ISP on the 2nd external interface. Since I will have 2 public address (one on each interface). I will then publish the same internal server on both public addresses. Sound reasonable? -----Original Message----- From: Chris Burns SRM [mailto:burnsc@xxxxxxxxxx] Sent: Thursday, June 20, 2002 1:00 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: External Interface & Multiple IPs http://www.ISAserver.org Ok, riddle me this then. You can have an external, and internal and a dmz all with thier own nic's. Isn't the DMZ considered external to the ISA? I don't really know th eanswer, but do believe I've seen many postings of people who've done multi-external nics. I presently only have one external, but have four external IP's assignned to it, and all are doing as thier supposed to do. ----- Original Message ----- From: "Paul Lemonidis (Hotmail)" <paul_lemonidis@xxxxxxxxxxx> To: "[ISAserver.org Discussion List]" <isalist@xxxxxxxxxxxxx> Sent: Thursday, June 20, 2002 1:46 PM Subject: [isalist] RE: External Interface & Multiple IPs > http://www.ISAserver.org > > > Hi All > > I am not certain but I think you can do the following.
