That is true, it doesn't do "true" load balancing, but you can split traffic between different networks. For example, I have traffic bound for the local University routed through one network because they also use that same provider, it beats routing the traffic halfway across the US to go across town. If one network goes down, I can then make the change to route all traffic through the other one. So, while it doesn't do true load balancing and fail-over, it'll suffice for what I need. (Although, now that I think about it more, I could probably put routes with higher metrics in to provide fail-over...Hmmmm) As for a "default NIC", that is true with any router, if you don't specifically route it an address, it will take the "default" route. I tried to do this with ISA2000, but after many hours of working on it I finally had to agree with the manuals and MS Knowledge Base that it truly only supported ONE External NIC regardless of how many you put in there. The 2004 version was a great thing for us because it would support so many networks. Once I got it in place, I was able to get right of several routers and switches, and even one extra server. So, while I'll agree with you that ISA 2004 doesn't do "everything" that everyone would want, I will not agree that it only supports one ISP, as I know better, and have working proof of that. -----Original Message----- From: Jim Harrison [mailto:Jim@xxxxxxxxxxxx] Sent: Friday, January 21, 2005 17:49 To: [ISAserver.org Discussion List] Subject: [isalist] RE: SSL Problems with ISA 2004 http://www.ISAserver.org This is true of obth products. Ues, you can have as many physical interfaces as you want, but only one "default NIC" where the default gateway lives. You will not achieve any sort of failover or load balancing with your installation.
